Abstract : For a finite simplicial graph $Gamma$, let $G(Gamma)$ denote the right-angled Artin group on the complement graph of $Gamma$. (Non-adjacent vertices of $Gamma$ correspond to commutative generators in $G(Gamma)$.) In the talk, we will discuss the following problem: for which graph $Lambda$ does there exist an embedding of $G(Gamma)$ into $G(Lambda
