Formal matched asymptotics for degenerate Ricci flow neckpinches

الأصل · EN

Gu and Zhu have shown that Type-II Ricci flow singularities develop from nongeneric rotationally symmetric Riemannian metrics on Sᵐ, for all m≥ 3. In this paper, we describe and provide plausibility arguments for a detailed asymptotic profile and rate of curvature blow-up that we predict such solutions exhibit.
