Virtual endomorphisms of the group $pg$

open access: yesResearches in Mathematics
A virtual endomorphism of a group $G$ is a homomorphism of the form $\phi:H\rightarrow G$, where ...

Properly stratified endomorphism algebras

open access: yesJournal of Algebra, 2005
The authors prove the following statement: Theorem. Let \(R\) be a commutative, local, self-injective algebra over an algebraically closed field. Let \({\mathcal X}=\{X(1)=R,X(2),\dots,X(n)\}\) be a sequence of local-colocal \(R\)-modules reflecting inclusions of the corresponding local ideals \(\underline X(i)\) of \(R\) (i.e. \(\underline X(i)\subset\

Lefschetz formula for nonlocal elliptic problems associated with fibration

open access: yesСовременная математика: Фундаментальные направления
Elliptic operator complexes associated with fibration are considered. The Atiyah-Bott-Lefschetz formula for endomorphisms of such complexes is given. The proof is based on the stationary phase method.

Hom-Jordan and Hom-alternative bimodules

open access: yesExtracta Mathematicae, 2020
In this paper, Hom-Jordan and Hom-alternative bimodules are introduced. It is shown that Jordan and alternative bimodules are twisted via endomorphisms into Hom-Jordan and Hom-alternative bimodules respectively.
