[Binghamton Geometry Topology Seminar] Seminar

[Matthew R Haulmark]

 Hi everyone,

This week we will be having our first talk of the semester. Our speaker
will be Christopher Perez from Loyola University New Orleans. Here are the
details.

*Title:* Towers and elementary embeddings in toral relatively hyperbolic
groups

*Abstract:  *In a remarkable series of papers, Zlil Sela classified the
first-order theories of free groups and torsion-free hyperbolic groups
using geometric structures he called towers. It was later proved by Chloé
Perin that if H is an elementarily embedded subgroup (or elementary
submodel) of a torsion-free hyperbolic group G, then G is a tower over H.
We prove a generalization of Perin's result to toral relatively hyperbolic
groups using JSJ and shortening technique*s *
