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.
