No. of bitstreams: 1 Tese - kelly karina Santos.pdf: 722332 bytes, checksum: e05b2f5cdf66907db561da0b2871dc37 (MD5) Previous issue date: 2016-11-04 / In this work we investigate some characteristics of the equivariant embeddings of a symmetric Kahlerian manifold. We use the Theorem of Wallach-Cartan to characterize these embeddings in the case of CP" and SO(2n)/U(n) and verify that if a equivariant embedding has parallel plurimean curvature then it's the extrinsic symmetric one. We use the standard embedding of CP" to prove that if a complex submanifold of CP" has parallel plurimean curvature, then it's the totally geodesics. We propos a new equivariant embedding, the p-embedding, for any hermitian symmetric space and verify that, at least when the rank is one, the plurimean curvature is not parallel. / Neste trabalho investigamos algumas características dos mergulhos equivariantes de uma variedade Kãhleriana Simétrica. Usamos o Teorema de Wallach-Cartan para caracterizar tais mergulhos nos casos do CPn e SO(2n)IU(n) e verificamos que nestes casos os únicos mergulhos com pluri-curvatura média paralela são os extrinsecamente simétricos. Usando o mergulho standard do CPn mostramos que se uma subvariedade complexa Q do ar tem pluri-curvatura média paralela então ela é totalmente geodésica. Propusemos ainda um novo mergulho equivariante, denominado p—mergulho, para um espaço simétrico hermitiano qualquer e verificamos alue, pelo menos no caso em que o posto de P é um, a pluri-curvatura média não é paralela .
