No. of bitstreams: 1 Arquivototal.pdf: 978771 bytes, checksum: bf0c05c8da5e986a77b6215a2235ab5e (MD5) Previous issue date: 2017-04-27 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / At the end of the 60s, Andr e and Quillen introduced a cohomology theory for commutative algebras, which today is called Andr e-Quillen's cohomology. In this work, we will study K ahler di erential functor, which is here seen as a derived functor (in a nonabelian context), which connects the categories: simpli ed R-algebras and simpli ed R-modules. In the rst, through simplicial resolutions, we will notice that they characterize certain objects and diagrams of this model category, which in turn, are preserved by K ahler di erential functor. In addition, we will approach the complex cotangent of a R-algebra, and through it, de ne the homology and cohomology of Andr e-Quilen, and of course, expose some properties of these. / No nal da década de 60, André e Quillen introduziram uma teoria de cohomologia para álgebras comutativas, que hoje recebe o nome de cohomologia de André-Quillen. Neste trabalho, estudaremos o funtor de diferenciais de K ahler, que aqui é visto como funtor derivado (em um contexto não abeliano), que conecta as categorias: R-álgebras simpliciais e R-m odulos simpliciais. Na primeira, atrav es das resolu c~oes simpliciais, notaremos que estas caracterizam certos objetos e diagramas desta categoria modelo, que por sua vez, s~ao preservados pelo funtor de diferenciais de K ahler. Al em disso, abordaremos o complexo cotangente de uma R- algebra, e atrav es dele, de nir a homologia e cohomologia de André-Quillen, e naturalmente, expor algumas propriedades destas.
