PINHEIRO, Neilha Márcia. Rigidez da esfera no espaço euclidiano. 2013. 41 f. Dissertação(Mestrado em Matemática) – Centro de Ciências, Universidade Federal do Ceará, Programa de Pós-Graduação em Matemática, Fortaleza, 2013. / Submitted by Erivan Almeida (eneiro@bol.com.br) on 2014-02-10T18:02:48Z No. of bitstreams: 1 2013_dis_nmpinheiro.pdf: 464377 bytes, checksum: bfe6fd9d9382d5993f7d0850c4acd7bd (MD5) / Approved for entry into archive by Rocilda Sales(rocilda@ufc.br) on 2014-02-11T13:21:07Z (GMT) No. of bitstreams: 1 2013_dis_nmpinheiro.pdf: 464377 bytes, checksum: bfe6fd9d9382d5993f7d0850c4acd7bd (MD5) / Made available in DSpace on 2014-02-11T13:21:07Z (GMT). No. of bitstreams: 1 2013_dis_nmpinheiro.pdf: 464377 bytes, checksum: bfe6fd9d9382d5993f7d0850c4acd7bd (MD5) Previous issue date: 2013 / In this work, we prove new rigidity results for almost-Einstein hypersurfaces of the Euclidean space, based on previous eigenvalue pinching results. Then, we deduce some comparable result for almost-umbilic hypersurfaces and new characterizations of geodesic spheres. / Neste trabalho, provamos novos resutados de rigidez para hipersuperfícies quase-Einsteins no espaço euclidiano, baseado-se nos resultados pinching do autovalor. Então, nós deduzimos alguns resultados análogos para hipersuperfícies quase-umbílicas e uma nova caracterização de esferas geodésicas.
