Uma introdução às identidades funcionais sobre a álgebra de matrizes triangulares superiores

Abstract

The subject treated in this dissertation is functional identities (FI) of a especific ring. We present concepts, examples and some results involving the themes: standard solution of a FI, strong degree of a ring, strongly d-free rings and FI-degree of a ring. In particular, it is studied the solutions of a particular FI on upper triangular matrices algebra, that is: Let ... to be continued
