Random and Arithmetic Structures in Topology Seminars
RAS Program Associate Seminar
Tuesdays 10:30-12:00 Pacific Time, beginning September 15th
To participate, please email Tommaso Cremaschi or James Farre.
The PA seminar is a learning seminar for early career mathematicians (graduate student and postdocs). Please only join the seminar if you are an early career mathematician.
In this expository talk, we discuss the basic properties and construction of lattices in the product of the automorphism groups of two trees. These groups were studied by Burger, Mozes, and others beginning in the 1990s. Using these techniques, one can construct groups that are finitely presented, torsion-free, simple, and split as a free product of free groups amalgamated along a subgroup of finite index. We also present some examples of these groups and analogies with Lie theory.Introduction to Burger—Mozes groups
