[pt] COHOMOLOGIA DE FIBRADOS FLAG HOMOGÊNEOS / [en] COHOMOLOGY OF HOMOGENEOUS FLAG BUNDLES

GUILHERME BRANDAO GUGLIELMO 10 June 2021 (has links)
[pt] Esta dissertação tem como objetivo exibir uma fórmula para cálcular o anel de cohomologia de um fibrado flag homogêneo de um grupo de Lie G compacto e conexo. Para concluir o resultado é usado a cohomologia equivariante, em particular, sua abordagem mais algébrica. Isto implica introduzir G- módulos e sua teoria equivariante, o que passa também por introduzir a álgebra de Weil, o modelo de Cartan e o homomorfismo característico. A demonstração do resultado também está fortemente baseada nas propriedades algébricas dos toros maximais de G. / [en] The purpose of this dissertation is to present a formula for calculating the cohomology ring of a homogeneous flag bundles of a compact and connected Lie G group. To conclude the result, the equivalent cohomology is used, in particular, its more algebraic approach. This implies introducing G modules and their equivalent theory, which also involves introducing Weil algebra, Cartans model and characteristic homomorphism. The income statement is also strongly based on the algebraic properties of the maximal torus of G.
