Double domination in signed graphs
A graph with either positive or negative labels on the edge becomes a signed graph. Given a signed graph $ \Sigma =(V,E,\sigma ) $, a subset D of V is said to be a double dominating set for $ \Sigma $, if it satisfies the following conditions: (i) every vertex u of $ \Sigma $ is either in D and u ha...
