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…
Graded identities with involution for the algebra of upper triangular matrices
Diogo Diniz, Alex Ramos
Let be a field of characteristic zero. We prove that if a group grading on admits a graded involution then this grading is a coarsening of a $\mathbb{Z}^{\lfloor\frac…
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…
Graded Isomorphisms on Upper Block Triangular Matrix Algebras
Alex Ramos, Claudemir Fidelis, Diogo Diniz
We describe the graded isomorphisms of rings of endomorphisms of graded flags over graded division algebras. As a consequence describe the isomorphism classes of upper block triang…
