Almost unit-clean rings

Chen H.; Kose H.; Kurtulmaz Y. (Editura Academiei Romane, 2019)

A ring R is almost unit-clean provided that every element in R is equivalent to the sum of an idempotent and a regular element. We prove that every ring in which every zero-divisor is strongly ?-regular is almost unit-clean ...
On ?-morphic modules

Harmanci A.; Kose H.; Kurtulmaz Y. (Hacettepe University, 2013)

Let R be an arbitrary ring with identity and M be a right R-module with S = End(MR). Let f ? S. f is called ?-morphic if M/fn(M) ? ?M(fn) for some positive integer n. A module M is called ?-morphic if every f ? S is ...
Strongly clean triangular matrix rings with endomorphisms

Chen H.; Kose H.; Kurtulmaz Y. (Iranian Mathematical Society, 2015)

A ring R is strongly clean provided that every element in R is the sum of an idempotent and a unit that commutate. Let Tn(R; ?) be the skew triangular matrix ring over a local ring R where ? is an endomorphism of R. We ...
