On a Variant of the Penrose Conjecture

Sven Hirsch, Yipeng Wang

We give a counterexample to a recently conjectured variant of the Penrose inequality.

Area-minimizing capillary cones

Benjy Firester, Raphael Tsiamis, Yipeng Wang

We construct non-flat minimal capillary cones with bi-orthogonal symmetry groups for any dimension and contact angle. These cones interpolate between rescalings of a singular solut…

Stability inequalities for one-phase cones

Benjy Firester, Raphael Tsiamis, Yipeng Wang

We obtain strict stability inequalities for homogeneous solutions of the one-phase Bernoulli problem. We prove that in dimension and above, cohomogeneity one solutions with bi-…

On fill-ins with scalar curvature bounded from below and an inequality of Hijazi-Montiel-Roldán

Simon Brendle, Raphael Tsiamis, Yipeng Wang

We consider fill-ins of spin manifolds with scalar curvature bounded by . Gromov proposed a conjecture relating the infimum of the mean curvature of such a fill-in to the…

Uniqueness of Cylindrical Tangent Cones

Benjy Firester, Raphael Tsiamis, Yipeng Wang

We show the uniqueness of the cylindrical tangent cone for area-minimizing hypersurfaces in , completing the u…

On Gromov's rigidity theorem for polytopes with acute angles

S. Brendle, Y. Wang

In his ``Four Lectures", Gromov conjectured a scalar curvature extremality property of convex polytopes. Moreover, Gromov outlined a proof of the conjecture in the special case whe…
