This page hosts information on Inder's talk "What is … a Bruhat-Tits tree?" at the "What is …?" seminar. The talk will take place on Friday, November 9, 4pm at HU, RUD 25 1.023.
In this talk I will define a Bruhat-Tits tree and describe the construction of the tree associated to PGL(2,F) for F a local field. If time permits, I will also discuss some applications
of the tree in representation theory.
