Complete reducibility and separability
No full textLet G be a reductive linear algebraic group over an algebraically closed field of characteristic p > 0. A subgroup of G is said to be separable in G if its global and infinitesimal centralizers have the same dimension. We study the interaction between the notion of separability and Serre's concept of G-complete reducibility for subgroups of G. The separability hypothesis appears in many general theorems concerning G-complete reducibility. We demonstrate that many of these results fail without this hypothesis. On the other hand, we prove that if G is a connected reductive group and p is very good for G, then any subgroup of G is separable; we deduce that under these hypotheses on G, a subgroup H of G is G-completely reducible provided the Lie algebra of G is semisimple as an H-module.Recently, Guralnick has proved that if H is a reductive subgroup of G and C is a conjugacy class of G, then the intersection of C and G is a finite union of H-conjugacy classes. For generic p -- when certain extra hypotheses hold, including separability -- this follows from a well-known tangent space argument due to Richardson, but in general, it rests on Lusztig's deep result that a connected reductive group has only finitely many unipotent conjugacy classes. We show that the analogue of Guralnick's result is false if one considers conjugacy classes of n-tuples of elements from H for n > 1

A construção do conhecimento no meio virtual: uma experiência com adolescentes do ensino básico interagindo sobre orientação sexual
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Educação. Programa de Pós-Graduação em Educação.Esta pesquisa, de natureza exploratória, pretende investigar como o conhecimento se constrói na interação entre seis estudantes de 8ª série do Ensino Fundamental, três de uma escola particular, localizada na cidade de Curitiba (PR), e três de outra escola particular, localizada na cidade de Florianópolis (SC), interagindo em uma sala de bate papo da internet sobre o tema Orientação Sexual. Visa ainda analisar a viabilidade deste meio de comunicação como proposta de aprendizagem nas extensões de sala de aula na tentativa de aproximar o virtual e o presencial e abrir novos caminhos para o ensino do professor e para a aprendizagem dos alunos. O foco proposto para a análise foi direcionado ao tipo de informação que os alunos compartilham e a influência da escola nessa interação; ao tratamento dado à sexualidade; a como as máximas ou princípios conversacionais cooperativos manifestam-se no discurso dos interagentes e, por último, à avaliação dos estudantes sobre a experiência vivida. Os dados foram analisados a luz da teoria sócio-histórico-cultural de Vygotsky e dos princípios cooperativos propostos por Grice. Os resultados sugerem que a construção do conhecimento em salas de bate papo é proporcionada pela possibilidade do interagente refletir sobre os próprios pensamentos e opiniões com base nas informações compartilhadas por outros interagentes. A construção do conhecimento ocorre através da interação mutua que proporciona desenvolvimento e aprendizagem de novos conceitos
