zweak ideals and prime weak ideals
(Tehran, ACECR at Tarbiat Modares University, 20121101)In this paper, we study a generalization of zideals in the ring C(X) of continuous real valued functions on a completely regular Hausdorff space X. The notion of a weak ideal and naturally a weak zideal and a prime weak ...

$z^circ$filters and related ideals in $C(X)$
(Yazd University, 20151101)In this article we introduce the concept of $z^circ$filter on a topological space $X$. We study and investigate the behavior of $z^circ$filters and compare them with corresponding ideals, namely, $z^circ$ideals of ...

$Z_k$Magic Labeling of Some Families of Graphs
(University of Tehran, 20181201)For any nontrivial abelian group A under addition a graph $G$ is said to be $A$textit{magic} if there exists a labeling $f:E(G) rightarrow A{0}$ such that, the vertex labeling $f^+$ defined as $f^+(v) = sum f(uv)$ ...
