Abstract:

In 2008, Liedtke introduced a group functor $\tilde{\mathcal{K}}$ that was used to described certain invariants of algebraic surfaces. We describe a relationship between this functor and a construction of Rocco that has a strong connection with Schur multipliers of groups. Some results, examples, and open questions will be presented. This is joint work with Heiko Dietrich (Monash University).
