Abstract: |
Besides the space of positive scalar curvature metrics, various moduli spaces have gained a lot of attention. Among those, the observer moduli space arguably behaves best from a homotopy-theoretical perspective because the subgroup of observer diffeomorphisms acts freely on the space of Riemannian metrics if the underlying manifold is connected. In this talk, I will present how to construct non-trivial elements in the observer moduli space of positive scalar curvature metrics for a large class for four-manifolds. If time permits, I will also outline how to adapt this construction to produce non-trivial elements in higher homotopy groups of the observer moduli space of positive sectional curvature metrics on complex projective spaces. |
