### Speaker

David González Álvaro (University of Fribourg)

### Description

The goal of this talk is to discuss the following result: for a manifold homotopy equivalent to $RP^5$, the moduli space of metrics with non-negative sectional (resp. with positive Ricci) curvature has infinitely many path connected components. The proof involves various elements such as Brieskorn spheres, Grove-Ziller metrics, reduced eta-invariants and fixed point formulas. This is joint work with Anand Dessai.​
