Summary: Let $G= (V,E)$ be a graph with chromatic number $k$. A dominating set $D$ of $G$ is called a chromatic transversal dominating set (ctd-set) if $D$ intersects every color class of any $k$-coloring of $G$. The minimum cardinality of a ctd-set of $G$ is called the chromatic transversal domination number of G and is denoted by $\gamma_{ct}(G)$. We initiate a study of this parameter.
