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
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.
