Abstract:Let [Formula: see text] be a finite abelian group. As a consequence of the results of Di Vincenzo and Nardozza, we have that the generators of the [Formula: see text]-ideal of [Formula: see text]-graded identities of a [Formula: see text]-graded algebra in characteristic 0 and the generators of the [Formula: see text]-ideal of [Formula: see text]-graded identities of its tensor product by the infinite-dimensional Grassmann algebra [Formula: see text] endowed with the canonical grading have pairly the same degr… Show more
“…We observe that the same happens for the Grassmann algebra E in positive characteristic endowed with its canonical Z 2 -grading (see Theorem 7.1 of [6] for more details).…”

“…In this example we are focusing on θ 1 and we will work with the equation β 0 1 θ 1 +β 3 1 θ 4 + β 6 1 θ 7 = 0. Since F is an infinite field, then there exist distinct β 1,0 , β 1,1 , β 1,2 ∈ F − {0}.…”

Let F be an infinite field of characteristic different from two and E be the infinite dimensional Grassmann algebra over F . We consider the upper triangular matrix algebra UT 2 (E) with entries in E endowed with the Z 2 -grading inherited by the natural Z 2 -grading of E and we study its ideal of Z 2 -graded polynomial identities (T Z2 -ideal) and its relatively free algebra. In particular we show that the set of Z 2 -graded polynomial identities of UT 2 (E) does not depend on the characteristic of the field. Moreover we compute the Z 2 -graded Hilbert series of UT 2 (E) and its Z 2 -graded Gelfand-Kirillov dimension.

“…In this section we collect the results concerning the Z 2 -graded identities of E based on the works by the author [7] and Di Vincenzo and da Silva [14]. For the sake of completeness we want to cite the papers [37] and [2] by Anisimov in which the author computes the sequence of involutive codimensions of Grassmann algebra for some special involutions (see [37]), then generalized in [2].…”
“…Recently, Di Vincenzo and da Silva gave in [6] a complete description of the Z 2 -graded polynomial identities of E with respect to any Z 2 -grading such that the generating space is Z 2 -homogeneous. This work has been generalized by the author for any infinite field of characteristic p > 2 (see [2]). In [1] Anisimov constructed an algorithm to compute the exact value of the graded codimension of E for any Z p -grading of E, where p is a prime number.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
