The spacetime of a shift endomorphism [PDF]

Transactions of the American Mathematical Society, 2016
The automorphism group of a one dimensional shift space over a finite alphabet exhibits different types of behavior: for a large class with positive entropy, it contains a rich collection of subgroups, while for many shifts of zero entropy, there are ...

ENDOMORPHISM CONGRUENCES

Demonstratio Mathematica, 1995
The notion of endomorphism congruence considered in this paper has a close connection with the notion of result. To say most generally, results are fractions such that their numerators are elements of a certain linear space while their denominators are injective endomorphisms of that space.

Endomorphism Algebras of Abelian varieties with special reference to Superelliptic Jacobians [PDF]

, 2016
This is (mostly) a survey article. We use an information about Galois properties of points of small order on an abelian variety in order to describe its endomorphism algebra over an algebraic closure of the ground field. We discuss in detail applications

Cogenerator endomorphism rings [PDF]

Proceedings of the American Mathematical Society, 1971
If R R is a ring and P P is a finitely generated projective right R R -module, what properties of R R does the R R -endomorphism ring of P P inherit? Rosenberg and Zelinsky have shown that if R R is quasi-Frobenius, and P

Principally Quasi-Injective Semimodules

مجلة بغداد للعلوم, 2019
In this work, the notion of principally quasi- injective semimodule is introduced, discussing the conditions needed to get properties and characterizations similar or related to the case in modules.

On periodic points of free inverse monoid endomorphisms

, 2012
It is proved that the periodic point submonoid of a free inverse monoid endomorphism is always finitely generated. Using Chomsky's hierarchy of languages, we prove that the fixed point submonoid of an endomorphism of a free inverse monoid can be ...

Enumerating Problems Concerning Endomorphisms of Double Vertex Wheel Graphs

Journal of Mathematics
We can define six classes of endomorphisms on a graph, and they always form a chain based on set inclusion. The concepts of endomorphism type and endomorphism spectrum were introduced by Böttcher and Knauer in 1992.

Solvability of invariant systems of differential equations on H2$\mathbb {H}^2$ and beyond

Mathematische Nachrichten, EarlyView.
Abstract We show how the Fourier transform for distributional sections of vector bundles over symmetric spaces of non‐compact type G/K$G/K$ can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange theorem.

Endomorphism rings of modules over prime rings [PDF]

, 2012
Endomorphism rings of modules appear as the center of a ring, as the fix ring of ring with group action or as the subring of constants of a derivation. This note discusses the question whether certain *-prime modules (introduced by Bican et al.) have a ...

Frobenius morphisms and derived categories on two dimensional toric Deligne-Mumford stacks

, 2013
For a toric Deligne-Mumford (DM) stack, we can consider a certain generalization of the Frobenius endomorphism. For such an endomorphism on a two-dimensional toric DM stack, we show that the push-forward of the structure sheaf generates the bounded ...
