The Connectivity Of Domination Dot-Critical Graphs With No Critical Vertices
An edge of a graph is called dot-critical if its contraction decreases the domination number. A graph is said to be dot-critical if all of its edges are dot-critical. A vertex of a graph is called critical if its deletion decreases the domination number.
