We will discuss the 'group extension' problem, which asks: given groups G and N, in what ways may we construct a group E which has N as a normal subgroup and quotient E/N isomorphic to G? A brief introduction to group cohomology will be given, along with its connections to the extension problem. Time permitting, we will also mention the analogous theory for Lie algebras (i.e. Lie algebra extensions and Lie algebra cohomology).
