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).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Algebra Seminar Speaker:&nbsp; Primo\u017e Moravec ( University of Ljubljana) Topic:&nbsp;Two group functors extending Schur multipliers Place:&nbsp; This is an online seminar.
