We prove stability of integrable ALE manifolds with a parallel spinor under Ricci flow, given an initial metric which is close in
The result is obtained by a fixed point argument, based on novel estimates for the heat kernel of the Lichnerowicz Laplacian. It allows us to give a precise description of the convergence behaviour of the Ricci flow. Our decay rates are strong enough to prove positive scalar curvature rigidity in
