Montreal Geometric & Combinatorial Group Theory Seminar

Speaker: Alexei Myasnikov (McGill)

Title: “Algebraic extensions in free groups”

Date: 3:30pm Wednesday, November 6.

Room: 920 Burnside

Abstract:

I am going to show how one can develop a theory of algebraic extensions of subgroups of free groups. This is analogues to the classical theory of algebraic extensions of fields. The analogy is surprisingly close. I will discuss some non-trivial applications of this theory to open problems in combinatorial group theory.
