Variedades com curvatura prescrita : resultados de existÃncia, unicidade, rigidez e bifurcaÃÃo / Manifolds with prescribe curvature: results of existence uniqueness, rigidity and bifurcation

Tiago CaÃla Ribeiro 03 February 2012 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Apresentamos vÃrios resultados de existÃncia, unicidade, rigidez e bifurcaÃÃo para o problema da prescriÃÃo de diversas estruturas geomÃtricas em variedades Riemannianas, entre os quais incluem-se: i) deformaÃÃo e rigidez para estruturas 2k-Einstein em variedades com (2k − 2)-curvatura seccional constante; ii) deformaÃÃo conforme de mÃtricas no contexto do problema de Yamabe para curvaturas de Gauss-Bonnet; iii) unicidade, bifurcaÃÃo e rigidez local no Ãmbito do problema de Yamabe para as funÃÃes simÃtricas dos autovalores do tensor de Schouten. / We present several results of existence, uniqueness, rigidity and bifurcation for the problem of prescribing various geometric structures on Riemannian manifolds, among which include: i) deformation and rigidity for 2k-Einstein structures on manifolds with constant (2k − 2)-sectional curvature; ii) conformal deformation of metrics in the context of the Yamabe Problem for Gauss-Bonnet curvatures; iii) uniqueness, bifurcation and local rigidity in scope of the Yamabe Problem for symmetric functions of eigenvalues of the Schouten tensor.
