No. of bitstreams: 1 santiagomilerquispemamani.pdf: 952447 bytes, checksum: 6008ae3816024f866eea3c17d560372d (MD5) Previous issue date: 2016-04-25 / O objetivo deste trabalho é apresentar o resultado dado por Bass em [4], que determina uma condição no domínio de integridade R para que todo módulo finitamente gerado e livre de torção seja escrito como soma direta de módulos de posto 1. Mostramos que uma condição necessária é que todo ideal em R seja gerado por dois elementos, ou seja, que esses domínios sejam quase domínios de Dedekind. Em seguida, aplicamos o resultado na descrição de módulos livres de torção e de posto finito sobre os anéis de coordenadas de curvas singulares, cujas singularidades são nós ou cúspides. / The aim of this paper is to present the result given by Bass in [4], which determines a condition on the integral domain R so that every finitely generated torsion free module is written as a direct sum of modules of rank 1. We show that a necessary condition is that all ideal in R is generated by two elements, in other words, that these domains are almost Dedekind domains. Then, we apply the result in the description of torsion free modules of finite rank over the coordinate rings of singular curves, whose singularities are nodal or cuspidal.
