Louis Yudowitz (KTH Stockholm): Abstract: When studying the compactness theory for solutions to geometric PDEs, one can encounter the formation of singularities. This occurs, for instance, for sequences of harmonic maps, Einstein manifolds, minimal surfaces, and gradient shrinking Ricci solitons. Provided the singular set consists of isolated points, a common strategy to study them is to construct a “bubble tree” through an iterative blow-up procedure. Moreover, supplementing this with analytic, geometric, and topological arguments allows for the recovery of information lost due to the bubbling behavior. In this talk I will discuss bubbling for gradient Ricci shrinkers, with a focus on how it affects the stability of singularity models for Ricci flow. In particular, I will give an overview of how to prove upper and lower semi-continuity of the Morse index for Ricci shrinkers by studying a certain weighted eigenvalue problem. I will also explain how the same techniques can be applied to show a quantitative relation between the stability of an asymptotically conical Ricci shrinker and that of its asymptotic cone. |

Fabian Rupp (Universität Wien): Abstract: The curve shortening flow arises as the L^2-gradient flow of the length functional. In this talk, we will discuss a novel energy method that reinterprets “curve shortening” as “tangent aligning”. This interpretation allows us to apply energy-based methods to study the long-time behavior of the curve shortening flow of curves of infinite length. Our method also applies to higher order flows such as the curve diffusion flow, Chen’s flow, and the elastic flow, which involves not only the curve shortening but also the curve straightening effect. This is joint work with T. Miura (Kyoto). |
