[Turkmath:2692] general seminar

[burcu.temur]

Dear colleagues, 

You are cordially invited to the general seminar
organized by the Department of Mathematics, Atılım University.

Our
speaker is YOSUM KURTULMAZ , Bilkent University. 

The title of her talk
is "VERY CLEANNESS OF GENERALIZED MATRICES". 

You can find the abstract
of her talk below. 

Abstract: An element $a$ in a ring $R$ is very
clean in case there exists
an idempotent $ein R$ such that $ae = ea$ and
either $a- e$ or $a
+ e$ is invertible. An element $a$ in a ring $R$ is
very $J$-clean
provided that there exists an idempotent $ein R$ such
that $ae =
ea$ and either $a-ein J(R)$ or $a + ein J(R)$. Let $R$ be
a
local ring, and let $sin C(R)$. We prove that $Ain K_s(R)$ is
very
clean if and only if $Ain U(K_s(R))$; $Ipm Ain U(K_s(R))$
or $Ain
K_s(R)$ is very J-clean. 

DATE: DECEMBER 06, 2017 

TIME: 15:40


PLACE: FEF 404 
With my best regards,
