Talk: "On Algorithmic Recognition of Certain Classes of Groups" (J. Delgado, UPC)

GC Cryptography Student Seminar

The Graduate Center (CUNY, NYC)

Abstract:
I will introduce the standard framework for recognition problems in group theory, then move to a more specific setting: namely group extensions by infinite cyclic groups.

For this family, I will review some folklore facts and previous partial results which we use to provide an argument that implies the undecidability of the BNS invariant (a nice geometrical invariant on which I would also like to say a few words).

This is joint work with B. Cavallo, D. Kahrobaei, and E. Ventura.
