In this paper we characterize the independent dominating sets in some graphs resulting from graph operations such as the corona, lexicographic product, and Cartesian product of graphs. Upper bounds… Expand

A subset C of V (G), where G is a connected graph, is convex in G if for every pair of vertices x, y ∈ C, the vertex set of every x-y geodesic in G is contained in C. Moreover, if C is also a… Expand

In this paper, we take another look at the definition of the Henstock integral of function with values in a topological vector space (TVS). It is known that for a Banach-valued function, the… Expand

In this paper we characterize the total restrained dominating sets in the join, corona, lexicographic product, cartesian product, and tensor product of two connected graphs. The corresponding upper… Expand
