k-Tuple total domination and Mycieleskian graphs
Let $k$ be a positive integer. A subset $S$ of $V(G)$ in a graph $G$ is a $k$-tuple total dominating set of $G$ if every vertex of $G$ has at least $k$ neighbors in $S$. The $k$-tuple total domination number $gamma _{times k,t}(G)$ of $G$ is the minimum cardinality of a $k$-tuple total dominating se...
