Modules in which kernels of endomorphisms are invariant under all automorphisms
A right R-module M is called kernel-invariant (under automorphisms) if the kernels of all endomorphisms of M are invariant under all automorphisms of M. We show that the classes of kernel-invariant modules and rings inherit some of the important features

Endomorphism and automorphism graphs of finite groups
Let $G$ be a group. The directed endomorphism graph, $\dend(G)$ of $G$ is a directed graph with vertex set $G$ and there is a directed edge from the vertex $a$ to the vertex $b$ if $a \neq b$ and there exists an endomorphism on $G$ mapping $a$ to $b$. The endomorphism graph, $\uend(G)$ is the corresponding undirected simple graph.

Rings generated by the inner-automorphisms of non-abelian groups
, 1971 The endomorphisms of an abelian group form a ring. The characterization of groups in which endomorphisms generate a ring is still an open question. It is shown here that the inner-automorphisms of a group generate a ring if and only if the conjugate ...

Outer endomorphisms of free metabelian Lie algebras [PDF]
, 2011 Let Fm be the free metabelian Lie algebra of rank m over a field K of characteristic 0. We consider the semigroup IE(Fm) of the endomorphisms of Fm which are identical modulo the commutator ideal of Fm.

Central limit theorem for commutative semigroups of toral endomorphisms
, 2013 Let $\Cal S$ be an abelian finitely generated semigroup of endomorphisms of a probability space $(\Omega, {\Cal A}, \mu)$, with $(T_1, ..., T_d)$ a system of generators in ${\Cal S}$.

Automorphisms of the endomorphism semigroup of a free commutative algebra
, 2009 We describe the automorphism group of the endomorphism semigroup $\End(K[x_1,...,x_n])$ of ring $K[x_1,...,x_n]$ of polynomials over an {\it arbitrary} field $K$. A similar result is obtained for automorphism group of the category of finitely generated free commutative-associative algebras of the variety $\mathcal{CA}$ commutative algebras. This solves

Inertial endomorphisms of an abelian group
, 2013 We describe inertial endomorphisms of an abelian group $A$, that is endomorphisms $\varphi$ with the property $|(\varphi(X)+X)/X|
