No. of bitstreams: 1 Benedito Leandro Neto.pdf: 688417 bytes, checksum: c1ac127d257e0a8d59d30de577413351 (MD5) Previous issue date: 2011-09-02 / In this work, we started with an historical study of Ricci Solitons showing that they, often, arise as a auto-similar solution for the Ricci flow. It was demonstrated, then, some basic concepts of Riemannian Geometry and a formal definition of a Ricci Solitons. To conclude the work, it was presented a study analysis of the [6] article, establishing , among other results, two theorems: the first one, an estimation for the potential function of a Gradient Shrinking Ricci Solitons, complete non-compact, and, the second one, an estimation for the volume of a Gradient Shrinking Ricci Solitons, complete non-compact. / Nesse trabalho, nós começamos com um levantamento histórico sobre os Ricci Sólitons, mostrando que, muitas vezes, eles surgem como solução auto-similar do fluxo de Ricci. Em seguida, introduzimos alguns conceitos básicos de geometria Riemanniana e definimos formalmente um Rici Sóliton. Concluimos o trabalho com um estudo aprofundado do artigo [6], do qual mostramos, dentre outros resultados, dois teoremas: uma estimativa para a função potencial de um Ricci Sóliton Gradiente Shrinking, completo e não-compacto e uma estimativa superior para o volume de um Ricci Sóliton Gradiente Shrinking, completo e não-compacto.
