A pesquisa foi desenvolvida com alunos do primeiro ano do curso de Ciências Biológicas da Unesp, campus de Rio Claro, na disciplina Matemática Aplicada. O professor convidou os alunos para que, reunidos em grupos, investigassem um tema qualquer do cotidiano, escolhido por eles. Os dados foram coletados por meio da observação de aulas da disciplina e das reuniões em horário extra, das entrevistas com os grupos dos Projetos de Modelagem e dos documentos produzidos pelos alunos. Estabeleci esses procedimentos de pesquisa pois considero que estão em harmonia com a visão de conhecimento sintetizada pelo construto teórico do coletivo Seres-Humanos-com- Mídias, evidenciando o papel das TIC na produção de conhecimentos. A análise de dados aponta que os alunos utilizaram a Internet para realizar parte das suas pesquisas, com uma seleção, a priori, de sites, os quais, identifiquei como sendo, para eles, sites oficiais. Os estudantes também utilizaram softwares gráficos para realizar simulações, que nomeei como sendo positivas, negativas e nebulosas, possibilitando previsões para o passado e para o futuro. Também fiz um exercício inicial de reflexão sobre o uso do email feito pelos alunos, para que possibilitasse a discussão do trabalho e a produção do relatório escrito. Esses temas de análise possibilitaram engendrar possíveis aspectos sobre a combinação das perspectivas reorganização e a cidadania (relativas ao uso das TIC na Educação Matemática) com a perspectiva dos Projetos de Modelagem. Com isso, esta pesquisa gera novas reflexões para a área, compondo parte do Mosaico de pesquisas em Modelagem. / In this study, I investigated how students use Information and Communication Technologies (ICT) in Mathematical Modeling Projects. The research was developed with first-year Biology majors at Unesp, Rio Claro campus, participating in an Applied Mathematics course. The professor invited the students to form groups and choose any theme from their everyday lives to investigate in the class. The data were collected by means of: in-class observations as well as observations of meetings held outside of class; interviews with the Modeling Project groups; and analysis of the documents they produced. I established these research procedures because I considered them to be in harmony with the view of knowledge synthesized in the theoretical construct of the Humans-with-Media collective, providing evidence of the role of ICT in the production of knowledge. Data analysis indicated that students used the Internet to carry out part of their research, with an a priori selection of the sites, which I identified as being official sites for them. The students also used graphing software to conduct simulations, which I characterized as positive, negative, or nebulous, making possible predictions positive and negative. I also did an initial reflective exercise about students' use of e-mail to facilitate discussion of the work and production of the written report. These analytic themes made it possible to identify possible aspects of the combination of the perspectives of reorganization and citizenship (related to the use of ICT in Mathematics Education) with the perspective of modeling projects. The study generates new reflections for this field of study, composing part of the mosaic of research on Modeling.

Este novo método é uma combinação entre as duas metodologias usadas para calcular estes coeficientes, que são o método diferencial e o método da teoria da perturbação generalizada. O método consiste em fazer como parâmetro integral o fluxo médio em uma região arbitrária do sistema. Dessa forma, o coeficiente de sensibilidade passa a conter somente o termo correspondente ao fluxo de nêutrons. Para obtenção do novo coeficiente de sensibilidade é feito o cálculo do coeficiente de sensibilidade desse parâmetro integral com relação a σ através do método de perturbação e são obtidas as derivadas funcionais do parâmetro integral genérico com relação a σ e Φ utilizando o método diferencial. / Dissertação (Mestrado em Tecnologia Nuclear) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

<p dir="ltr">The concept of infinity plays a pivotal role in mathematics, yet its precise definition remains elusive. This conceptual ambiguity has given rise to several puzzles in contemporary philosophy of mathematics. In response, this dissertation embarks on a rational reconstruction of Hegels concept of infinity and applies it to resolve two groups of mathematical puzzles, including challenges in applied mathematics, especially the application of differential calculus, and the conceptual ground of set theory, especially Cantors paradox.</p><p dir="ltr">The exploration begins with a historical survey of the concept of infinity in philosophy. It becomes evident that a prevailing interpretation characterizes infinity as the unlimited. In addition, this unlimitedness has taken various forms, including endlessness (Aristotle), all-inclusiveness (Spinoza), and self-sufficiency (Kant).</p><p dir="ltr">The heart of the dissertation lies in reconstructing Hegels concept of genuine infinity. Hegel argues that the unlimited as the negation of the limit entails either the completely indeterminate or another limited entity, neither of which is genuinely infinite. Instead, Hegel points out that genuine infinity is the self-relation of a limited entity. By self-relation, Hegel means that the limited entity alters into another limited entity that is isomorphic to the original one.</p><p dir="ltr">Subsequently, Hegel’s concept of genuine infinity can be translated into a mathematical framework as the intrinsic alteration of quantum (roughly speaking, quantum is Hegel’s term for the variable), which is captured by the corresponding relation among quanta. It is argued that this relation serves as the necessary condition for three mathematical entities traditionally considered infinite: arbitrarily large (small) numbers, infinite sets, and endless sequences. Thus, for Hegel, this intrinsic relation among quanta constitutes the essence of mathematical infinity.</p><p dir="ltr">Hegels concept of mathematical infinity can help us resolve difficulties within contemporary mathematics. First, it addresses the question of why infinite mathematical structures can be applied to describe and predict seemingly finite physical phenomena. The application of mathematics is usually explained by the similarity between mathematical structures and empirical systems, but the lack of apparent empirical counterpart leads one to doubt the application of infinite mathematical structures. Hegels concept of mathematical infinity directs us to focus on the structural similarity between infinite mathematical structures and empirical systems, specifically between the intrinsic alteration of quantum and the change of physical properties with time. With this structural similarity, the application of mathematics can be explained. Second, the dissertation investigates the conceptual ground of set theory, especially the relationship between a set and its members. Hegels analysis of genuine infinity provides a twofold clarification: (1) members of set must be a unit first, which entails that the set of all sets (the Universe) is not a set; (2) members of a set are simultaneously distinct (due to their independent logical content) yet indistinguishable (due to their common structure as a unit). Clarification 1 resolves Cantors paradox as it excludes the Universe; clarification 2 explains arithmetic operations.</p>

Unter der Voraussetzung, dass q keine Einheitswurzel ist und dass die Differentiale duij der Fundamentalmatrix den Linksmodul der 1-Formen erzeugen, werden die bikovarianten Differentialkalküle auf den Quantengruppen SLq(N), Oq(N) und Spq(N) klassifiziert. Es wird gezeigt, dass es auf den Quantengruppen SLq(N), N ≥ 3, abgesehen von eindimensionalen Kalkülen und endlich vielen Werten von q genau 2N bikovariante Differentialkalküle gibt. Diese Kalküle haben die Dimension N². Für die Quantengruppen Oq(N) und Spq(N), N ≥ 3, gibt es unter den genannten Voraussetzungen bis auf endlich viele Werte von q genau zwei bikovariante Differentialkalküle der Dimension N². Die Bimodulstruktur der Kalküle sowie die zugeordneten ad-invarianten Rechtsideale werden explizit angegeben. Für die Quantengruppen SLq(N), N ≥ 3, wird gezeigt, dass es, sofern q keine Einheitwurzel ist, genau 2N² + 2N bikovariante Bimoduln vom Typ (u^c u; f) gibt. / If q is not a root of unity and under the assumption that the differentials duij of the fundamental matrix (uij) generate the left module of 1-forms, all bicovariant differential calculi on quantum groups SLq(N), Oq(N) and Spq(N) are classified. It is shown that on quantum groups SLq(N), N ≥ 3, except of 1-dimensional calculi and finitely many values of q, thre are exactly 2N bicovariant differential calculi. The space of invariant forms has dimension N². For quantum groups Oq(N) and Spq(N), N ≥ 3, under the same assumptions and up to finitely many values of q, there are exactly two bicovariant differential calculi of dimension N². The bimodule structure of the calculi as well as the corresponding ad-invariant right ideals are explicitely described. For quantum groups SLq(N), N ≥ 3, there are exactly 2N² + 2N bicovariant bimodules of type (u^c u; f) provided q is not a root of unity.
