Neste trabalho, dissertamos sobre uma teoria abstrata para a equação de variedades bidimensionais (ou simplesmente superfícies), a saber, a teoria dos pares de Codazzi, formas espaciais R³, S³ e H³. Precisamente, generalizamos alguns teoremas clássicos da teoria de superfícies e unificamos a prova de outros resultados, aparentemente não relacionados. Além disso, estudamos a existência de diferenciais quadráticas holomorfas, estimativas de altura e aplicamos a referida teoria abstrata na classificação das superfícies de Weingarten especiais elípticas, completas e mergulhadas em R³, cuja curvatura Gaussiana não muda de sinal.

In this work, based on the article The Codazzi Equation for Surfaces by Juan A. Aledo, José M. Espinar and José A. Gálvez [8], we describe some applications of an abstract theory for the Codazzi equation on surfaces. This theory deals with abstract pairs of quadratic forms on a surface, in particular the so-called Codazzi pairs, for which the Codazzi equation is satisfied. Among the applications, we give a proof of an abstract version of a classical theorem due to Hopf on immersed spheres in Euclidean space R3 with constant mean curvature. Other applications are proofs of Liebmann s theorem on complete surfaces with constant Gaussian curvature in R3 and of Grove s theorem on the rigidity of ovaloids. We also study the existence of holomorphic quadratic differentials associated with Codazzi pairs. This is used, in particular, in the classification of complete embedded elliptic special Weingarten surfaces of non-minimal type in R3 whose Gaussian curvature does not change sign.
Nesta dissertação, baseada no artigo The Codazzi Equation for Surfaces de Juan A. Aledo, José M. Espinar e José A. Gálvez [8], descrevemos algumas aplicações de uma teoria abstrata para a equação de Codazzi em superfícies. Nessa teoria são estudados de modo abstrato, pares de formas quadráticas definidos em uma superfície satisfazendo certas propriedades, em particular os chamados pares de Codazzi, para os quais a equação de Codazzi é satisfeita. Dentre as aplicações, apresentamos uma demonstração de uma versão abstrata do clássico teorema de Hopf sobre superfícies homeomorfas à esfera imersas em R3 com curvatura média constante. Outras aplicações são demonstrações do teorema de Liebmann sobre superfícies completas em R3 com curvatura Gaussiana constante positiva e do teorema de Grove sobre rigidez dos ovalóides. Estudamos também a existência de diferenciais quadráticas holomorfas associadas a pares de Codazzi, as quais são usadas, em particular, na classificação das superfícies de Weingarten especiais elípticas de tipo não-mínimo, completas e mergulhadas em R3, cuja curvatura Gaussiana não muda de sinal.

Neste trabalho apresentamos um estudo de pares de Codazzi em superfícies de variedades homogêneas tridimensionais. Inicialmente, apresentamos um resultado abstrato para pares de Codazzi em superfícies completas com curvatura Gaussiana não-positiva e o aplicamos para obter resultados do tipo Efimov e Milnor para superfícies completas nas formas espaciais não- Euclidianas. Para superfícies de espaços produto, a técnica de pares de Codazzi é utilizada na apresentação de um resultado do tipo Liebmann para superfícies completas com curvatura Gaussiana constante. Nos espaços homogêneos E(k; t ); com t ≠ 0; apresentamos um par de Codazzi definido sobre superfícies de curvatura média constante, cuja sua (2; 0)-parte é a diferencial de Abresch-Rosenberg.
In this work, we present a study of Codazzi pairs on surfaces of 3-dimensional homogeneous manifolds. Initially, we present an abstract result about Codazzi pairs on complete surfaces with non-negative Gauss curvature and we apply it to obtain Efimov and Milnor's type results for complete surfaces in non-Euclidian space forms. For surfaces in product spaces, the technique of Codazzi pairs is applied in the presentation of a Liebmann's type result for complete surfaces with constant Gaussian curvature. In the homogeneous spaces E(k; t ); with t ≠ 0, we present a Codazzi pair defined on surfaces with constant mean curvature, whose (2; 0)-part is the Abresch- Rosenberg difierential.

School dropout is a phenomenon that occurs at educational institutions, both public and private. The actions of the government regarding education find themselves disconnected from the reality of problems like abandonment, retention or even premature passing, where the variables that interfere in each student?s school process are not perceived. The objective of this research was to discover the causes of dropout in the Business Administration and Marketing technical course (CTADEM) at Col?gio Dom Agostinho Ikas (CODAI), in the period between 2010 and 2013, conceptualizing dropout and its developments, mapping the causes of school dropout, highlighting its motivations from the point of view of students and teachers, and presenting possible actions that aim to minimize it. With this intent we utilize a qualitative methodology interlaced with the exploratory character Case Study technique. As instruments, we use questionnaires with registered students and students who have dropped out and interviews with the students at CTADEM. In the analysis of our discoveries, we investigate the motives and reasons that lead to a student dropping out, dealing with the perceptions of social players, understanding their concepts about school dropout, motivations of school permanence, searching for contributions that can be useful toward the decrease of dropout rates at CTADEM, their limits and possibilities, interlaced with the views of theorists involved in this investigation. In this way we have noticed a reality that points to several aspects, such as family problems, geographical aspects, unprepared high school graduates, outdated physical infrastructure and school environment, hindering better integration and educational quality, as well as the need to evaluate CTADEM according to the current MEC criteria and restructuring of its curriculum. These perceptions can contribute not only to make teachers aim a continuous improvement of their activities, but also to aid CTADEM in its efforts toward a better school performance, constructing strategies to confront school drop out with possible reflections in the quality of instruction, and the educational, social and economic development of these students
A evas?o escolar ? um fen?meno que acomete as institui??es de ensino, sejam elas p?blicas ou privadas. As a??es do governo diante da educa??o encontram-se desconectadas da realidade em problemas como abandono, repet?ncia ou mesmo na aprova??o, onde n?o se percebem as vari?veis que interferem no processo escolar do aluno. Esta pesquisa teve como finalidade conhecer as causas da evas?o no Curso T?cnico em Administra??o Empresarial e Marketing (CTADEM) do Col?gio Agr?cola Dom Agostinho Ikas (CODAI), no per?odo compreendido entre 2010 e 2013, conceituando a evas?o escolar e seus desdobramentos, mapeando as causas da evas?o escolar, destacando suas motiva??es sob o ponto de vista dos discentes e docentes, apresentando possibilidades de a??es que visem minimiz?-la. Para este intento utilizamos a metodologia qualitativa entrela?ado com a t?cnica de Estudo de Caso de car?ter explorat?rio. Utilizamos como instrumentos question?rios mistos com os discentes ingressos e evadidos e entrevistas semiestruturada com os docentes do CTADEM. Na an?lise das descobertas investigamos os motivos e raz?es que levam o aluno a se evadir, tratando das percep??es dos atores sociais compreendendo seus conceitos sobre evas?o, motiva??es da perman?ncia, buscando contribui??es que possam ser utilizadas visando a diminui??o da evas?o no CTADEM, seus limites e possibilidades, entrela?ados com os olhares dos te?ricos envolvidos nesta pesquisa. Nesse caminhar apreendemos uma realidade que aponta diversos aspectos, como problemas familiares, aspectos geogr?ficos, o despreparo oriundo do ensino m?dio, infraestrutura f?sica e ambiente escolar inadequados com as modernidades, dificultando uma melhor integra??o e qualidade de ensino, bem como necessidade de avalia??o do CTADEM pelos crit?rios atuais do MEC e reestrutura??o da grade curricular. Essas percep??es podem contribuir n?o apenas para que os docentes visem uma melhoria cont?nua de suas atividades, mas tamb?m auxiliar o CTADEM na busca de um melhor desempenho da institui??o como escola, construindo estrat?gias para o enfrentamento da evas?o escolar com poss?veis reflexos na qualidade de ensino, desenvolvimento educacional, social e econ?mico desses alunos
