Equivariant Allen--Cahn Solutions and the Existence of Cohomogeneity Minimal Surfaces
Rayssa Caju, Pedro Gaspar, Jared Marx-Kuo
We develop a regularity theory for equivariant Allen--Cahn solutions on closed Riemannian manifolds with a Lie group acting isometrically. When the cohomogeneity of the action is b…

Infinitely Many Surfaces with Prescribed Mean Curvature in the Presence of a Strictly Stable Minimal Surface
Pedro Gaspar, Jared Marx-Kuo
We construct infinitely many distinct hypersurfaces with prescribed mean curvature (PMC) for a large class of prescribing functions when is a closed smooth manifold…

Almgren's Three-Legged Starfish
Christos Mantoulidis, Jared Marx-Kuo
In this note we use classical tools from min-max and hyperbolic geometry to substantiate a folklore example in Almgren--Pitts min-max theory, the three-legged starfish metric on a…
