The rst one, conceived as a tool for the study of problems related to Dirichlet series, is a generalization of Littlewood`s 4/3 inequality to multilinear forms. The second is a generalization of Bohnenblust-Hille inequality, produced by the replacement of c0 with lp. / No presente trabalho abordaremos duas desigualdades cl assicas, a saber, a Desigualdade de Bohnenblust-Hille e a Desigualdade de Hardy- Littlewood. A primeira, surgiu como ferramenta para o estudo de problemas relacionados a s eries de Dirichlet e e uma generaliza c~ao para formas multilineares da Desigualdade 4/3 de Littlewood. A segunda consiste de uma generaliza c~ao da Desigualdade de Bohnenblust-Hille, produzida pela substituição de c0 por lp.

The first concerns about the Bohnenblust-Hille and Hardy- Littlewood multilinear inequalities. We obtain optimal and definitive generalizations for both inequalities. Moreover, the approach presented provides much simpler and straightforward proofs than the previous one known, and we are able to show that in most cases the exponents involved are optimal. The technique used is a combination of probabilistic tools and of an interpolative approach; this former technique is also employed in this thesis to improve the constants for vector-valued Bohnenblust-Hille type inequalities. The second subject has as starting point the existence of Peano spaces, that is, Haurdor spaces that are continuous image of the unit interval. From the point of view of lineability we analyze the set of continuous surjections from an arbitrary euclidean spaces on topological spaces that are, in some natural sense, covered by Peano spaces, and we conclude that large algebras are found within the families studied. We provide several optimal and definitive result on euclidean spaces, and, moreover, an optimal lineability result on those special topological vector spaces. / Este trabalho édividido em dois temas. O primeiro diz respeito às desigualdades multilineares de Bohnenblust-Hille e Hardy-Littlewood. Obtemos generalizações ótimas e definitivas para ambas desigualdades. Mais ainda, a abordagem apresentada fornece demonstrações mais simples e diretas do que as conhecidas anteriormente, além de sermos capazes de mostrar que os expoentes envolvidos são ótimos em varias situações. A técnica utilizada combina ferramentas probabilísticas e interpolativas; esta ultima e ainda usada para melhorar as estimativas das versões vetoriais da desigualdade de Bohnenblust-Hille. O segundo tema possui como ponto de partida a existência de espaços de Peano, ou seja, os espaços de Hausdor que são imagem contínua do intervalo unitário. Sob o ponto de vista da lineabilidade, analisamos o conjunto das sobrejecoes contínuas de um espaço euclidiano arbitrário em um espaço topológico que, de certa forma, e coberto por espaços de Peano, e concluímos que grandes álgebras são encontradas nas famílias estudadas. Fornecemos vários resultados ótimos e definitivos em espaços euclidianos, e, mais ainda, um resultado de lineabilidade ótimo naqueles espaços vetoriais topológicos especiais.

Cette thèse porte sur la poétique du roman de Victor Hugo, Theodor Fontane et Thomas Hardy en s'appuyant plus spécifiquement sur l'étude de L'Homme qui rit (1869), Errements et Tourments (1888) et Tess d'Urberville (1891). En rapprochant ces trois romanciers majeurs mais tenus à l'écart des théories générales du roman, il s'agit de montrer le maintien d'une conception du roman moderne comme forme poétique du monde, s'inscrivant dans un horizon de pensée idéaliste, progressiste et critique. Hugo, Fontane et Hardy, romanciers qui se disent avant tout poètes, font le choix de faire du roman une tragédie, forme poétique du monde qui va à l'encontre du prosaïsme moderne et romanesque théorisé par Lukacs, à la suite de Hegel. Face au nihilisme et aux théories du roman réaliste qui voient le jour dans la seconde moitié du XIXe siècle et tentent de définir – au sens restrictif du terme – le genre romanesque, ils retrouvent le modèle du roman romantique et le redéfinissent face au roman réaliste. Leur poétique est alors fondée sur la « poiétisation » de la prose, autrement dit, sur l'imagination, le symbolique et le métaphorique. Ils affirment ainsi la spécificité et la possibilité d'une expérience poétique, c'est-à-dire subjective, héroïque et morale du monde, ainsi que la capacité du roman à produire un savoir poétique sur le monde et l'histoire. / This thesis deals with the poetics of the novel in Victor Hugo, Theodor Fontane and Thomas Hardy, with a specific focus on The Man who Laughs (1869), Trials and Tribulations (1888) and Tess of the d'Urbervilles (1891). By bringing together these three novelists who are widely acknowledged as major writers yet ignored by general theories of the novel, this study will show how a vision of the modern novel as a poetic rendition of reality, with an idealist, progressive and critical background, has maintained itself. Hugo, Fontane and Hardy, three novelists who considered themselves to be poets first and foremost, opted to turn the novel into a tragedy, a poetic rendition of reality which stands in contrast with Lukacs’ post-Hegelian theories of the modern novel as a prosaic literary genre. In the face of nihilism and the theories of the realist novel which surfaced in the second half of the XIXth century and attempted to define – in the restrictive sense of the word – the genre of the novel, they turned back to the model of the Romantic novel and reinvented it at a time when the realist novel was preeminent. Their poetics was therefore based on the “poietisation” of prose, in other words, based on the imaginary, the symbolic and the metaphoric. This enabled them to assert the specificity and possibility of a poetic, that is to say subjective, heroic and moral experience of the world, as well as the ability of the novel to generate poetical knowledge about the world and history.

Cette thèse porte sur quelques inégalités de type Trudinger-Moser et leurs applications à l'étude des injections de Sobolev qu'elles induisent dans les espaces d'Orlicz et à l'analyse d'équations aux dérivées partielles non linéaires à croissance exponentielle.Le travail qu'on présente ici se compose de trois parties. La première partie est consacrée à la description du défaut de compacité de l'injection de Sobolev 4D dans l'espace d'Orlicz dansle cadre radial.L'objectif de la deuxième partie est double. D'abord, on caractérise le défaut de compacité de l'injection de Sobolev 2D dans les différentes classes d'espaces d'Orlicz. Ensuite, on étudiel'équation de Klein-Gordon semi-linéaire avec non linéarité exponentielle, où la norme d'Orlicz joue un rôle crucial. En particulier, on aborde les questions d'existence globale, de complétude asymptotique et d'étude qualitative.Dans la troisième partie, on établit des inégalités optimales de type Adams, en étroite relation avec les inégalités de Hardy, puis on fournit une description du défaut de compacité des injections de Sobolev qu'elles induisent / This thesis focuses on some Trudinger-Moser type inequalities and their applications to the study of Sobolev embeddings they induce into the Orlicz spaces, and the investigation of nonlinear partial differential equations with exponential growth.The work presented here includes three parts. The first part is devoted to the description of the lack of compactness of the 4D Sobolev embedding into the Orlicz space in the radialframework.The aim of the second part is twofold. Firstly, we characterize the lack of compactness of the 2D Sobolev embedding into the different classes of Orlicz spaces. Secondly, we undertakethe study of the nonlinear Klein-Gordon equation with exponential growth, where the Orlicz norm plays a crucial role. In particular, issues of global existence, scattering and qualitativestudy are investigated.In the third part, we establish sharp Adams-type inequalities invoking Hardy inequalities, then we give a description of the lack of compactness of the Sobolev embeddings they induce

A dissertação apresenta os resultados obtidos com o desenvolvimento de um programa de computação abrangente em interface gráfica para ambiente Windows visando a estimativa de parâmetros de interesse genético-populacional (freqüências alélicas, respectivos erros-padrão e intervalos de confiança a 95%) e o teste de hipóteses genéticas (equilíbrio de Hardy-Weinberg e análise de estruturação hierárquica populacional), por meio de métodos tradicionais e por meio de testes exatos obtidos com procedimentos de simulação (bootstrap e jackknife). / The dissertation presents the results obtained with the development of a comprehensive computation program (software), running on the Windows (MS) graphic interface, with the aim of: (a) estimating parameters of population genetic interest (such as allelic frequencies and their corresponding standard errors and 95% confidence intervals); and (b) performing the testing of genetic hypotheses (Hardy-Weinberg population ratios and analysis of population hierarchical structure) by means of traditional methods as well as through exact tests obtained with computer simulation procedures (bootstrap and jackknife methods).

Psychiater: 'Amerikas Jungen in der Krise', titelt Die Welt am 2. Juni 1998 und ruft unter Bezug auf den Psychiater William Pollock von der Harvard University 'eine nationale Krise des Knabenalters' aus. Nachdem '[j]ahrelang (...) in den USA die Förderung von Mädchen Priorität' hatte, offenbaren die Statistiken nun eine erschütternde Bilanz: 'Im Pubertätsalter begehen in den USA fünfmal so viele Jungen wie Mädchen Selbstmord. Jungen machen 90 Prozent der Disziplinarfälle aus und brechen viermal häufiger die Schule ab.' Während es unter männlichen Jugendlichen zu immer mehr Gewalttaten, wie beispielsweise der weltweit durch die Medien gegangenen Serie von Bluttaten an amerikanischen Schulen kommt, die 2002 in einem Film wie Bowling for Columbine sogar noch einen künstlerisch-kritischen Ausdruck findet, und sich Deutschland noch von den Schockwellen des Erfurter Massakers erholt, leiden nach einer in L'Actualité médicale publizierten kanadischen Studie im Kindes- und Jugendalter deutlich mehr Männer als Frauen an Beeinträchtigungen beziehungsweise Erkrankungen.

This thesis compares and contrats the abnormal escapism of characters created by Eugene O'Neill, Henrich Ibsen, and Thomas Hardy.

Indiana University-Purdue University Indianapolis (IUPUI) / The main part of this thesis, Chapter 4, contains results on the commutant of a semigroup of operators defined on the Hardy Space of the disk where the operators have hyperbolic non-automorphic symbols. In particular, we show in Chapter 5 that the commutant of the semigroup of operators is in one-to-one correspondence with a Banach algebra of bounded analytic functions on an open half-plane. This algebra of functions is a subalgebra of the standard Newton space. Chapter 4 extends previous work done on maps with interior fixed point to the case of the symbol of the composition operator having a boundary fixed point.
