Talk: "Enriched pullbacks and the intersection problem" (J. Delgado, UPC)

We extend to the family of free-abelian times free groups the classical Stallings theory describing subgroups
of the free group as automata. This approach provides an alternative way of understanding several algorithmic results, and a promising way for attacking new ones.

In particular, I will discuss its application to the intersection problem within this family using an adaptation of the pull-back technique to this new framework.
