Embeddability of right-angled Artin groups on complements of trees

Eon-Kyung Lee, Sang-Jin Lee

For a finite simplicial graph $\Gamma$, let $A(\Gamma )$ denote the right-angled Artin group on $\Gamma$. Recently Kim and Koberda introduced the extension graph ${\Gamma }^e$ for $\Gamma$, and established the…
