-domination in graphs
Abdollah Khodkar, Babak Samadi, H. R. Golmohammadi
We first introduce the concept of (k,k',k'')-domination numbers in graphs, which is a generalization of many domination parameters. Then we find lower and upper bounds for this par…

New bounds on the signed domination numbers of graphs
S. M. Hosseini Moghaddam, Abdollah Khodkar, Babak Samadi
In this paper, we study the signed domination numbers of graphs and present new sharp lower and upper bounds for this parameter. As an example, we present a lower bound on signed d…

A solution to an open problem on lower against number in graphs
Babak Samadi
In [1] the problem of finding a sharp lower bound on lower against number of a general graph is mentioned as an open question. We solve the problem by establishing a tight lower bo…
