On minimal edge version of doubly resolving sets of a graph
Muhammad Ahmad, Zohaib Zahid, Sohail Zafar
In this paper, we introduce the edge version of doubly resolving set of a graph which is based on the edge distances of the graph. As a main result, we computed the minimum cardina…
On the Betti numbers of some classes of Binomial edge ideals
Zohaib Zahid, Sohail Zafar
We study the Betti numbers of binomial edge ideal associated to some classes of graphs with large Castelnuovo-Mumford regularity. As an application we give several lower bounds of…
Algebraic properties of the binomial edge ideal of complete bipartite graph
Peter Schenzel, Sohail Zafar
Let denote the binomial edge ideal of a connected undirected graph on vertices. This is the ideal generated by the binomials in the…
On approximately Cohen-Macaulay binomial edge ideal
Sohail Zafar
Binomial edge ideals IG of a graph G were introduced by [4]. They found some classes of graphs G with the property that IG is a Cohen-Macaulay ideal. This might happen only for few…
