H-module endomorphism rings [PDF]
We discuss the endomorphism ring extension of a module over an H-comodule algebra. A necessary and sufficient condition for such an endomorphism ring extension to be Hopf Galois is obtained.

The endomorphism monoid of Pn¯ [PDF]
In this paper, the endomorphism monoid of Pn¯, the complement of a path Pn with n vertices, is explored explicitly. It is shown that End(Pn¯) is orthodox. Some enumerative problems concerning End(Pn¯) are solved.

Additive unit structure of endomorphism rings and invariance of modules [PDF]
We use the type theory for rings of operators due to Kaplansky to describe the structure of modules that are invariant under automorphisms of their injective envelopes. Also, we highlight the importance of Boolean rings in the study of such modules. As a

Endomorphisms of fibred groups [PDF]
A collection = {Gα|α∈A} of proper subgroups Gα of a group G is a fibration of G ifIt is of geometric interest to associate two semigroups to a group G with fibration :

MODULES WITH ABELIAN ENDOMORPHISM RINGS [PDF]
The results of Szele and Szendrei [‘On Abelian groups with commutative endomorphism rings’, Acta Math. Acad. Sci. Hungar.2 (1951), 309–324] characterizing abelian groups with commutative endomorphism rings are generalized to modules whose endomorphism ...

Remarks on log Calabi--Yau structure of varieties admitting polarized endomorphism [PDF]
We discuss the Calabi--Yau type structure of normal projective surfaces and Mori dream spaces admitting a non-trivial polarized endomorphism.

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 for a class of negative Calabi-Yau categories [PDF]
We consider an orbit category of the bounded derived category of a path algebra of type A_n which can be viewed as a -(m+1)-cluster category, for m >= 1.

The spacetime of a shift endomorphism [PDF]
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 ...
