"Right-angled Artin subgroups of higher-dimensional Thompson
groups "

Abstract:It is known that the free product of abelian groups Z^2*Z does
not embed into Thompson's group V (Bleak and Salazar-Díaz, 2013).
Moreover, this free product is the only obstruction for right-angled
Artin groups to be embedded into V (Corwin and Haymaker,2016).
In this talk, I will give a construction of embeddings of right-angled
Artin groups into higher-dimensional Thompson groups. It follows that a
right-angled Artin group embeds into n-dimensional Thompson group, where
n is less than or equal to the number of edges of the complement of the
defining graph.
