Resumo

Let F be an infinite field of characteristic different from 2, and let E be the Grassmann algebra of an infinite dimensional F-vector space L. In this paper we study the Z-graded polynomial identities of E with respect to certain Z-grading such that the vector space L is homogeneous in the grading. More precisely, we construct three types of Z-gradings on E, denoted by E-infinity, E-k{*} and E-k, and we give the explicit form of the corresponding Z-graded polynomial identities. We show that the homogeneous superalgebras E-infinity, E-k{*} and Ek studied in {[}12] can be obtained from E-infinity, E-k{*} and E-k as quotient gradings. Moreover we exhibit several other types of homogeneous Z-gradings on E, and describe their graded identities. (C) 2021 Elsevier Inc. All rights reserved. (AU)
