On the Existence and Uniqueness of Ancient Rescaled Mean Curvature Flows
Letian Chen
We show existence of ancient solutions to the rescaled mean curvature flow starting from a given asymptotically conical self-expander. These are examples of mean curvature flows co…

Rotational symmetry of solutions of mean curvature flow coming out of a double cone II
Letian Chen
We show that any integral Brakke flow coming out of a rotationally symmetric double cone with entropy at most two must stay rotationally symmetric for all time, provided the flow i…
