O presente estudo pretende analisar o processo de industrialização nos municípios paulistas de Botucatu, Avaré e Ourinhos. Para tanto se utiliza como referenciais teóricos as concepções dos geógrafos Milton Santos (2004 [1977]) sobre a categoria de análise formação socioespacial e André Cholley (1964) combinações geográficas, pois ambas articulam dialeticamente natureza e sociedade. Sobre a economia brasileira, especificamente a industrialização, adotamos, sem desconsiderar outras interpretações, as concepções de Ignácio Rangel (2005 [1957, 1985]) que aborda basicamente a dialética de poder através de meias revoluções ou as dualidades da economia brasileira; pactos de poder interno e externo. Segundo essa visão, o Brasil sendo uma formação social periférica, reage de forma dinâmica aos impulsos vindos do centro do sistema (ciclos kondratiev) sempre combinando modos de produção distintos ao longo de suas etapas de desenvolvimento histórico. No que tange o processo de industrialização no Estado de São Paulo, a perspectiva teórica abordada destaca o papel da pequena produção mercantil na dinâmica socioeconômica (processo de acumulação interna; industrialização via imigrantes e não pela via da oligarquia paulista). As razões da escolha do tema se devem ao fato de que pouca ênfase se tem dado à capacidade de iniciativa/inovação empresarial, existentes em diversas partes do país, que para se desenvolverem necessitam de uma política econômica favorável. Em suma, partimos do pressuposto de que a capacidade empresarial brasileira é gigantesca, entretanto, falta uma política econômica contínua que dê sustentação a esses empreendimentos. Aliás, determinadas decisões tomadas em âmbito governamental, como a instrução 70 (Getúlio Vargas) e a Instrução 113 (Juscelino Kubitschek) foram fundamentais para o crescimento econômico, já que as políticas de substituição de importações, também foram políticas protecionistas e desenvolvimentistas. Ou seja, sem elas, como diria Rangel, a indústria nacional teria uma contingência natural de nascer na crise internacional e desaparecer nas fases de recuperação econômica. Procura-se contribuir para o estudo da Geografia, tendo em vista a compreensão do processo de industrialização paulista, além de retomar um antigo tema da Geografia: as atividades industriais. / This research intends to analyze the industrial process in the municipalities of Botucatu, Avaré and Ourinhos, all of them parts of the São Paulo state. To achieve this goal it will be used as theoretical references the conceptions from the geographers such as Milton Santos (2004 [1977]) on the category of socio-spatial formation and analysis, André Cholley (1964) geographic combinations, since both articulate dialectically nature and society. On the Brazilian economy, specifically industrialization, we adopt, without disregarding other interpretations, the conceptions of Ignacio Rangel (2005 [1957, 1985]) that basically addresses the power of dialectic through half revolutions, or the dualities of the Brazilian economy; pacts internal and external power. According to this view, Brazil being a peripheral social formation, that reacts dynamically to the impulses coming from the system center (Kondratiev cycles) always combining different production methods throughout their historical development stages. Regarding the process of industrialization in São Paulo state, the addressed theoretical perspective emphasizes the role of small commodity production in the socio-economic dynamics (internal process of accumulation, industrialization via immigrants and not via the Paulista oligarchy). The reasons behind this choice of subject are due the fact that has been given little emphasis in the capacity of initiative / entrepreneurial innovation, which exist in different parts of the country that and needs to develop a favorable economic policy. In short, we assume that the Brazilian entrepreneurship is huge, however, lacks an economic policy that could continue to give support to these enterprises. In fact, certain decisions taken in the governmental level, such as the entitled \"Instruction 70\" (Getulio Vargas) and \"Instruction 113\" (Juscelino Kubitschek) were fundamental for economic growth, since import substitution policies were also protectionist and developmental policies. That is, without them, as Rangel would affirm, the domestic industry would have a contingency to born in the international crisis and to disappear in the stages of economic recovery. Therefore, it seeks to contribute to the study of geography and resume an old theme, which are the studies about industrial activities, intending to understanding the São Paulo state industrialization process.

This dissertation is focused on an algebraic approach of some many-valued generalizations of modal logics. The starting point is the definition of the [0,1]-valued and the Ł_n-valued Kripke models, where [0,1] denotes the well known MV-algebra and Ł_n its finite subalgebra {0, 1/n, ... , (n-1)/n,1} for any positive integer n. Two types of structures are used to define validity of formulas: the class of L-frames and the class of Ł_n-valued L-frames. The latter structures are L-frames in which we specify in each world u the set Ł_m (where m is a divisor of n) of the possible truth values of the formulas in u. These two classes of structures define two distinct notions of validity. We use these notions to study the problem of definability of classes of structures with modal formulas. We obtain for these two classes an equivalent of the Goldblatt-Thomason theorem. We are able to consider completeness problems with respect to these relational semantics thanks to the connections between relational and algebraic semantics. Our strongest results are about Ł_n-valued logics. We are indeed able to apply and develop algebraic tools (namely, canonical and strong canonical extensions) that allow to generate complete Ł_n-valued logics. / Nous consacrons cette dissertation à une étude algébrique de certaines généralisations multivaluées des logiques modales. Notre point de départ est la définition des modèle de Kripke [0,1]-valués et Ł_n-valués, où [0,1] désigne la MV-algèbre bien connue et Ł_n sa sous-algèbre {0, 1/n, ... , (n-1)/n,1} pour tout naturel non nul n. Nous utilisons deux types de structures pour définir une relation de validité: la classe des L-structures et celles des L-structures Ł_n-valuées. Ces dernières sont des L-structures dans lesquelles nous précisons pour chaque monde u l'ensemble Ł_m (où m est un diviseur de n) des valeurs de vérité que les formules sont autorisées à prendre en u. Ces deux classes de structures définissent deux notions distinctes de validité. Nous les utilisons pour étudier le problème de la définissabilité des classes de structures à l'aide du langage modal. Nous obtenons dans les deux cas l'équivalent du théorème de Goldblatt-Thomason. Nous considérons aussi les problèmes de complétude vis-à-vis de ces sémantiques relationnelles à l'aide des liens qui les lient à la sémantique algébrique. Les résultats les plus forts que nous obtenons concernent les logiques modales Ł_n-valuées. En effet, dans ce cas, nous pouvons appliquer et développer des outils algébriques (à savoir, les extensions canoniques et les extensions canoniques fortes) qui permettent de générer des logiques complètes.

The goal of the original research presented in this thesis is to study the strong coupling regime of Quantum Field Theories (QFTs) with different methods, making concrete predictions about the phase structure and the dynamics of these theories, and on their observables. The focus is on (gauge) field theories in three spacetime dimensions, which are an interesting laboratory to understand the properties of strong coupling in setups that are usually simpler than in the more familiar case of gauge theories in four dimensions. Importantly, topological effects play a relevant role in three dimensions, thanks to the presence of the so-called Chern-Simons term.The thesis contains a short introduction to QFTs in 3d, principles and applications of infrared dualities, large N techniques, and holography. Indeed, the web of infrared dualities, the large N expansion, and the holographic correspondence between QFT and gravity are the main tools which we use to investigate the strongly coupled regimes of 3d QFTs.Then, the original material is presented. In a first line of research, we focus on the study of the phase diagram of a 3d gauge theory making use of conjectured infrared dualities, extending such dualities to the case where more than one mass parameter can be dialed. In a second line of research, we study a class of 3d gauge theories by engineering their gravity dual in a string theory setup. We prove the existence of multiple phase transitions between phases characterized by both massless particles and topological sectors. In a third line of research, we use holography as a tool to explore the interplay between the physics of 4d QCD and 3d gauge theories. In particular, we analyze the properties of 3d domain walls, which appear as soliton-like solutions of 4d QCD in specific parametric regimes. Finally, we propose a boundary construction of 3d large N vector models, which appear as critical points of theories obtained by coupling degrees of freedom localized on a 3d boundary to a 4d bulk theory. This construction allows to prove new dualities and uncovers a new computational tool for 3d vector models. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Dans la description à basse énergie de systèmes fortement corrélés, les champs de jauge peuvent émerger comme excitations collectives couplées à des quasiparticules fractionalisées. En particulier, certains aimants bidimensionnels dits frustrés sont décrits par un liquide de spin de Dirac comportant une symétrie de jauge U(1) compacte. La description infrarouge est donnée par une théorie conforme des champs, soit l'électrodynamique quantique en 2+1 dimensions avec 2N saveurs de fermions sans masse. Dans les aimants typiques, N=2 ou 4. L'aspect compact du champ de jauge implique également l'existence d'excitations topologiques, soit des instantons créés, dans ce contexte, par des opérateurs monopôles. Cette thèse porte sur les transitions de phase quantiques à partir d'un liquide de spin de Dirac et les propriétés des monopôles aux points critiques correspondants. Ces transitions sont induites en activant diverses interactions de type Gross-Neveu. Dans tous les cas à l'étude, la dimension d'échelle des monopôles est obtenue grâce à la correspondance état-opérateur et à un développement en 1/N. L'accent est d'abord mis sur une transition de confinement-déconfinement vers une phase antiferromagnétique décrite par la condensation d'un monopôle. Une levée de dégénérescence est observée au point critique alors que certaines dimensions d'échelle de monopôles sont réduites par rapport à leur valeur dans le liquide de spin de Dirac. Cette hiérarchie est caractérisée quantitativement en comparant les dimensions d'échelle dans des secteurs distincts du spin magnétique à l'ordre dominant en 1/N, puis qualitativement par une analyse en théorie des représentations. Des exposants critiques pour d'autres observables dans la théorie non compacte sont également obtenus. Enfin, deux transitions vers des liquides de spin topologiques, soit le liquide de spin chiral et le liquide de spin Z2, sont considérées. Les dimensions anormales des monopôles sont obtenues à l'ordre sous-dominant en 1/N. Ces résultats permettent de vérifier une dualité conjecturée avec un modèle bosonique et la valeur d'un coefficient universel pour les théories de jauge U(1) / In strongly correlated systems, gauge fields can emerge as collective excitations coupled to fractionalized quasiparticles. In particular, certain frustrated two-dimensional quantum magnets are described by a Dirac spin liquid which has a U(1) gauge symmetry. The infrared description is given by a conformal field theory, namely quantum electrodynamics in 2+1 dimensions with 2N flavours of massless fermions. In typical magnets, N=2 or 4. The compact aspect of the gauge field also implies the existence of topological excitations corresponding to instantons, which are created by monopole operators in this context. This thesis focuses on quantum phase transitions out of a Dirac spin liquid and the properties of monopoles at the corresponding critical points. These transitions are driven by activating various types of Gross-Neveu interactions. In all the cases studied, the scaling dimension of monopoles are obtained using the state-operator correspondence and a 1/N expansion. The confinement-deconfinement transition to an antiferromagnetic order produced by a monopole condensate is first studied. A degeneracy lifting is observed at the critical point, as certain monopoles have their scaling dimension reduced in comparison with the value in the Dirac spin liquid. This hierarchy is charactized quantitatively by comparing monopole scaling dimensions in distinct magnetic spin sector at leading-order in 1/N, and qualitatively by an analysis in representation theory. Critical exponents of various other operators are obtained in the non-compact model. Transitions to two topological spin liquids, namely a chiral spin liquid and a Z2 spin liquid, are also considered. Anomalous dimensions of monopoles are obtained at sub-leading order in 1/N. These results allow the verification of a conjectured duality with a bosonic model and the value of a universal coefficient in U(1) gauge theories.

In dieser Arbeit untersuchen wir dualitätsinvariante höher-abgeleitete (alpha') Korrekturen an effektiven Stringtheorien mit niedriger Energie. Wir beschränken uns auf den universellen masselosen Sektor, bestehend aus Graviton, B-Feld und Dilaton, und spezialisieren uns auf Hintergründe mit d abelschen Isometrien, die O(d, d)-Invarianz genießen, und schließen Szenarien wie Kosmologie und Schwarze Löcher als Spezialfälle ein. Es wird erwartet, dass die O(d, d)-Symmetrie für beliebige Ableitungsordnungen erhalten bleibt, eine Tatsache, die Hohm und Zwiebach dazu motivierte, die kosmologische Klassifikation zu finden. Eine solche Konstruktion parametrisiert eine große Klasse rein zeitabhängiger dualitätsinvarianter Theorien für alle Ableitungsordnungen in Form einiger Koeffizienten. Stringtheorien stellen einzelne Punkte in diesem Theorieraum dar, die durch bestimmte Konfigurationen dieser Koeffizienten bestimmt werden. Wir berechnen die ersten Koeffizienten mit zwei Methoden: Verdichtungen und Beta-Funktionsberechnungen aus einer kosmologischen Weltenblattaktion. Anschließend untersuchen wir die Hohm-, Siegel- und Zwiebach-Theorie (HSZ) im kosmologischen Hintergrund, die die masselosen Stringmoden und neuartige massive Felder kodiert. Wir integrieren letztere heraus, um eine effektive Theorie für die masselosen Felder zu erhalten und lesen die entsprechenden Koeffizienten ab. Anschließend behalten wir die massiven Felder bei, finden eine zweifach abgeleitete Neuformulierung der Theorie, bestimmen die alpha'-genauen Friedmann-Gleichungen und erforschen die spannungsfreie Grenze. Wir überprüfen die Klassifikation für FRW-Hintergründe und stellen fest, dass alle Korrekturen trivial sind. Wir erweitern die Klassifikation auf zweidimensionale Hintergründe mit zeitähnlicher Isometrie, einem Raum, der Lösungen für schwarze Löcher zulässt. Wir finden alpha'-deformierte Schwarze Löcher mit und ohne Singularitäten. Letztere entsprechen regulären Kosmologien. / In this thesis we study duality-invariant higher-derivative (alpha') corrections to string low energy effective theories. We restrict to the universal massless sector, consisting of the graviton, B-field and dilaton, and specialize to backgrounds with d abelian isometries, which enjoy O(d, d)-invariance and contain scenarios such as cosmology and black holes as particular cases. The O(d, d)-symmetry is expected to be preserved to arbitrary orders in derivatives, a fact that motivated Hohm and Zwiebach to arrive at the cosmological classification. Such construction parameterizes a large class of purely-time dependent duality-invariant theories to all orders in derivatives in terms of a countable infinite number of coefficients. String theories represent single points in this theory space, determined by specific configurations of these coefficients. We compute the first coefficients by following two methods: compactifications and beta-function computations from a worldsheet action already in cosmological backgrounds. We then study the Hohm, Siegel, and Zwiebach (HSZ) theory in cosmological backgrounds, which encodes the massless string modes plus novel massive fields. We integrate out the latter to arrive at an effective theory for the massless fields and read the corresponding coefficients. We then keep the massive fields, find a two-derivative reformulation of the theory, determine alpha'-exact Friedmann equations and explore the tensionless limit. Coming back to generic duality-invariant theories, we revisit the classification for FRW backgrounds and find that all corrections are trivial. We extend the classification to two-dimensional backgrounds with time-like isometry, a space that admits black-hole solutions. We prove that the dual of a solution with a regular horizon must have a curvature singularity, and find alpha'-deformed black holes with and without singularities. The latter correspond to regular cosmologies.
