 07/07  Jordi Delgado (Math, UPC Barcelona) Title: Introduction to the BNS Invariant and Its Undecidability Abstract: I will introduce the BieriNeumannStrebel (BNS) invariant of a finitely generated group: a geometric invariant (in fact, a subset of R^n) which contains lots of interesting information about the group, but known to be, in general, hard to compute.
For example, the BNS invariant has the ability to detect finite generability of normal subgroups with abelian quotient. We will see that this fact can be used to deduce the undecidability of the invariant
