Incidence Rings: Automorphisms and Derivations
Piotr Krylov, Askar Tuganbaev
We study automorphisms, isomorphisms, and derivations of the incidence algebra , where is preordered set and is an algebra over some commutative ring .
Formal Matrix Rings: Isomorphism Problem
Piotr Krylov, Askar Tuganbaev
We consider the isomorphism problem for formal matrix rings over a given ring. Principal factor matrices of such rings play an important role in this case. The work is supported by…
On Realization and Isomorphism Problems for Formal Matrix Rings
Piotr Krylov, Askar Tuganbaev
We consider realization and isomorphism problems for formal matrix rings over a given ring. Principal multiplier matrices of such rings play an important role in this case.\\ The w…
Automorphisms of Formal Matrix Rings
Piotr Krylov, Askar Tuganbaev
We study automorphism groups of formal matrix algebras. We also consider automorphisms of ordinary matrix algebras (in particular, triangular matrix algebras).
