In this essay, Celeste Knopf describes her observations during her study abroad program at Centro Cultural e Histórico José Figueres Ferrer, in San Ramón, Costa Rica
Universality in mean curvature flow neckpinches
We study noncompact surfaces evolving by mean curvature flow. Without any

will become asymptotically rotationally symmetric in a space-time neighborhood
of its singular set, and will have a unique tangent flow.Comment: More references added, typos correcte
