Convergence of the Ricci flow to Ricci-flat ALE manifolds and positive scalar curvature rigidity
Abstract
We prove stability of integrable ALE manifolds with a parallel spinor under Ricci flow, given an initial metric which is close in $L^p \cap L^\infty$, for any $p \in (1, n)$, where $n$ is the dimension of the manifold. In particular, our result applies to all known examples of $4$-dimensional gravitational instantons. Our decay rates are strong enough to prove positive scalar curvature rigidity in $L^p$, for each $p \in \left[1, \frac{n}{n-2}\right)$, generalizing a result by Appleton.
