**Group Cohomology and Group Extensions**

Friday, November 8, 2013, 2:30pm

Ungar Building Room 402

**Abstract:**Group cohomology originates in topology but has a very interesting algebraic formulation in terms of group extensions with abelian kernels. I will discuss the classification problem for such extensions and use it to motivate the introduction of group cohomology.
