### Towers and elementary embeddings in total relatively hyperbolic groups (Christopher Perez, Loyola University New Orleans)

Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesIn 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, and independently Olga Kharlampovich and Alexei Myasnikov did the same using equivalent structures they called regular NTQ groups. It was later proved by Chloé Perin that if H is an […]
