  • Abstract: In its most classical formulation, the Cohen-Lyndon property encodes independence between the relators in a group presentation. It is an interesting structural property that has been proven to hold, in one form or another, for various classes of groups. In this talk I’ll tell you a little bit about this property, the classes of groups that satisfy it, and some of its applications.
