A subset S of vertices in a graph G is aglobal total dominating set, or just GTDS, if $S$ is a total dominating set of both G and $\overline{G}$. The global total domination number $\gamma_{gt}(G)$ of G is the minimum cardinality of a GTDS of G. We present bounds for the global total domination number in graphs.
