Made available in DSpace on 2014-07-29T16:02:20Z (GMT). No. of bitstreams: 1 Dissertacao Flavio P Vieira.pdf: 631827 bytes, checksum: b4c3dfd45d41b0313e21e87b61f0c94e (MD5) Previous issue date: 2012-04-12 / The main goal of this work is to establish a primary bound for the dimension of the second homology group of a group G, with coefficients in a field k of characteristic p, H2(G;k), using the operating system GAP. It will be presented with several examples, where in some cases, will be calculated the exact dimensions and in other cases only an upper bound. / O trabalho tem por objetivo principal estabelecer uma cota superior para a dimensão do segundo grupo de homologia de um grupo G, com coeficientes em um corpo k de característica p, H2(G;k), usando o sistema operacional GAP. Será apresentado uma gama de exemplos, onde em alguns casos, calcularemos exatamente a dimensão e em outras somente uma cota superior.
