This paper gives linear-time algorithms for finding two minimum (connected) dominating sets with minimum intersection for interval graphs.
A set D of vertices in a graph G =-(V,E) is called a point-set dominating (or, psd-) set of G if for every nonempty subset S of V -D there exists v E D such that the induced subgraph (S U {v}) is connected (cf. Sampthkumar and Pushpa Latha (1993) [6]). Here, we report results of our investigation in
## Abstract We determine necessary and sufficient conditions for a complete multipartite graph to admit a set of 1βfactors whose union is the whole graph and, when these conditions are satisfied, we determine the minimum size of such a set. Β© 2008 Wiley Periodicals, Inc. J Graph Theory 58:239β250,
