Topological complexity of configuration spaces
Abstract: The topological complexity of a space is a homotopy type invariant motivated by the motion planning problem from robotics. We discuss this invariant in the context of configuration spaces of ordered points on orientable surfaces.

Rigidity in equivariant stable homotopy theory
Abstract: Let G be a finite abelian group or finite (non-abelian) 2-group. We show that the 2-local G-equivariant stable homotopy category, indexed on a complete G-universe, has a unique G-equivariant model in the sense of Quillen model categories. This means that the suspension functor, homotopy cofiber sequences and the stable Burnside category determine all "higher order structure" of the 2-local G-equivariant stable homotopy category such as for example equivariant homotopy types of function G-spaces. The theorem can be seen as an equivariant generalization of Schwede's rigidity theorem at the prime 2.
