Title: A new platform semigroup for the Tillich-Zemor hash function scheme
In this talk, I will present a new candidate as platform for the
Tillich-Zemor general scheme of hash functions (1994) with the goal of
improving the security of the scheme. The underlying platform is the
noncommutative (semi)group of linear functions under composition. This a
joint work with V. Shpilrain.

Title: On Algorithmic Recognition of Certain Classes of Groups
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.
