Modules invariant under automorphisms of their covers and envelopes
PAG Asensio, DK Tütüncü, AK Srivastava - Israel Journal of Mathematics, 2015 - Springer
In this paper we develop a general theory of modules which are invariant under
automorphisms of their covers and envelopes. When applied to specific cases like injective …

On the girth of the unit graph of a ring
H Su, Y Zhou - Journal of Algebra and Its Applications, 2014 - World Scientific
The unit graph of a ring R, denoted G (R), is the simple graph defined on the elements of R
with an edge between vertices x and y iff x+ y is a unit of R. In this paper, we prove that the …

[HTML][HTML] Additive unit structure of endomorphism rings and invariance of modules
PAG Asensio, TC Quynh, AK Srivastava - Bulletin of Mathematical …, 2017 - Springer
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 …

On unit-central rings
D Khurana, G Marks, AK Srivastava - Advances in ring theory, 2010 - Springer
We establish commutativity theorems for certain classes of rings in which every invertible
element is central, or, more generally, in which all invertible elements commute with one …

Sums of units in rings
In this paper, we study rings that are additively generated by units. We prove that if the
identity in a ring with stable range one is a sum of two units, then every (von Neumann) …
