Synopsis:

Mean curvature flow provides a potential approach to finding special Lagrangians. To understand and overcome singularities that arise along the flow, it is essential to identify its generic singularity models. With Kahnrad Braxton and Jonathan Zhu, we find a new stable shrinker that may arise as a generic singularity of Lagrangian mean curvature flow. Topologically, this shrinker is a Möbius bundle and passing through such a singularity means undoing the real blowup.
