Abstract

Let Mn(K)M_n(K) be the algebra of n×nn \times n matrix over an infinite integral domain KK. Let gln(K)gl_n(K) be the Lie algebra of n×nn \times n matrix with the usual Lie product over KK. Let G={g1,,gn}G = \{g_1,\ldots,g_n\} be a group of order nn. We describe the polynomials that form a basis for the GG-graded identities of the pair (Mn(K),gln(K))(M_n(K),gl_n(K)) with an elementary GG-grading induced by the nn-tuple (g1,,gn)(g_1,\ldots,g_n). In the end, we describe an explicit basis for the Z3\mathbb{Z}_3-graded identities of the pair (M3(K),gl3(K))(M_3(K),gl_3(K)).
