Seminario de Teoría de Grupos
Seminario Teoría de grupos UAM-ICMAT CONSTRUCTING GROUP ACTIONS IN QUASI-TREES Ken Bromberg (Utah) Martes 25 de abril de 2017 – 14:30 h Aula 520, Módulo 17, Facultad de Ciencias, UAM (Campus de Cantoblanco, Madrid) Resumen: In joint work with M. Bestvina and K. Fujiwara we described an axiomatic approach to construct group actions on quasi-trees. The construction is very general and works for a wide class of groups that have some form of hyperbolic behavior. The original proof was quite technical. In new work, joint with Bestvina, Fujiwara and A. Sisto we have a much simpler approach that also produces acylindrical actions. We will describe this work.
