Superinvolutions on block-triangular matrix algebras
Laise Dias, Diogo Diniz, Alex Ramos
In this paper we classify, up to isomorphism, the superinvolutions on algebras of upper block-triangular matrices over an algebraically closed field of characteristic different fro…
On the Number of Gradings on Matrix Algebras
Diogo Diniz, Daniel Pellegrino
We determine the number of isomorphism classes of elementary gradings by a finite group on an algebra of upper block-triangular matrices. As a consequence we prove that, for a fini…
Identities and isomorphisms of finite-dimensional graded simple algebras
Angelo Bianchi, Diogo Diniz
Let be an algebraically closed field, be an abelian group, and let and be arbitrary finite-dimensional -graded simple algebras over . We prove…
Graded Identities and Isomorphisms on Algebras of Upper Block-Triangular Matrices
Alex Ramos, Diogo Diniz
Let be an abelian group and an algebraically closed field of characteristic zero. A. Valenti and M. Zaicev described the -gradings on upper block-triangular mat…
