Abstract

For a graph $G$, a set $L$ of vertices is called a total liar's domination if $|N_G(u)\cap L|\geq 2$ for any $u\in V(G)$ and $|(N_G(u)\cup N_G(v))\cap L|\geq 3$ for any distinct vertices $u,v\in V(G)$. The total liar’s domination number is the cardinality of a minimum total liar’s
dominating set of $G$ and is denoted by $\gamma_{TLR}(G)$. In this paper we study the total liar's domination numbers of join and products of graphs.
