Thema: Hardness results and approximation algorithms of k-tuple domination
       in graphs

Abstract:

In this talk, we study hardness results and approximation algorithms of
k-tuple domination in graphs. The k-tuple domination problem is a
generalization of the dominating set problem in graphs in which each
vertex of the graph h as to be dominated at least k times (instead of just
once).
