For main result we will describe a finite basis for Zn-graded polynomial identities of the matrix algebra of order n x n, with entries in a field F, This study will be divided into two stages: when the field F has characteristic zero and when the field F is infinite. These results were described by Vasilovsky [18] in 1999 and Azevedo [2] in 2006. / Nesta dissertação estudaremos álgebras G-graduadas e identidades polinomiais G-graduadas, onde G é um grupo aditivo. Como resultado principal descreveremos uma base finita para as identidades polinomiais Zn-graduadas da álgebra das matrizes n x n, com entradas em um corpo F, Este estudo será subdividido em duas etapas: quando o corpo F for de característica zero e quando o corpo F for infinito. Estes resultados foram descritos por Vasilovsky [18] em 1999 e por Azevedo [2] em 2006

Métodos diferentes são empregados conforme a característica do corpo: se Char K = 0, à descrição das identidades graduadas se reduz a descrição das identidades multilineares, o que foi feito no Capítulo 2, onde são descritas as identidade de Mn(K) com uma classe ampla de graduações elementares; se Char K =p>0 e K é in nito, a descrição das identidades graduadas é reduzida à descrição das identidades multi-homogêneas, que torna o problema mais difícil, e técnicas como a construção de álgebras genéricas são necessárias. No Capítulo 3 são descritas as identidades Z e Zn-graduadas de Mn(K) para um corpo in nito K. / The main theme of this dissertation is the description of the graded polynomial identities of the algebra Mn(K). Diferent methods are used depending on the characteristic of the field: if Char K = 0, the description of the graded identities is reduced to the description of the multilinear graded identities, what was done in Chapter 2, where the identities of Mn(K) are described for a wide class of elementary gradings; if Char K =p>0 and K is in nite, the description of the graded identities is reduced to the study of the multi-homogeneous identities, wich makes it harder, and techniques such as the construction of generic algebras are necessary. In Chapter 3 the Z and Zn-graded identities of Mn(K) are described for an infinite field K
