The intersection graph of ideals of $Z_{n}$ is\\ weakly perfect

R. Nikandish, M. J. Nikmehr

A graph is called weakly perfect if its vertex chromatic number equals its clique number. Let $R$ be a ring and $I (R)^{*}$ be the set of all left proper non-trivial ideals of $R$ . Th…

On weak $α$ -skew McCoy Rings

M. J. Nikmehr, A. Nejati, M. Deldar

Let $α$ be an endomorphism of a ring $R$ . We introduce the notion of weak $α$ -skew McCoy rings which are a generalization of the $α$ -skew McCoy rings and the weak McCo rings. Some…
