Center node: "new algorithms for weighted k domination and total k domination problems in proper interval graphs"
  Abstract: Given a positive integer $k$, a $k$-dominating set in a graph $G$ is a set of vertices such that every vertex not in the set has at least $k$ neighbors in the set. A total $k$-dominating set, also known as a $k$-tuple total dominating set, is a set of vertices such that every vertex of the graph has at least $k$ neighbors in the set. The problems of finding the minimum size of a $k$-dominating, resp. total $k$-dominating set, in a given graph, are referred to as $k$-domination, resp. total $k$-domination. These generalizations of the classical domination and total domination problems are known to be NP-hard in the class of chordal graphs, and, more specifically, even in the classes of split graphs (both problems) and undirected path graphs (in the case of total $k$-domination). On the other hand, it follows from recent work by Kang et al. (2017) that these two families of problems are solvable in time $\mathcal{O}(|V(G)|^{6k+4})$ in the class of interval graphs. In this work, we develop faster algorithms for $k$-domination and total $k$-domination in the class of proper interval graphs. The algorithms run in time $\mathcal{O}(|V(G)|^{3k})$ for each fixed $k\ge 1$ and are also applicable to the weighted case.
