Ricci flow on manifolds with positive isotropic curvature in all dimensions

Simon Brendle, Raphael Tsiamis

We extend the classification of manifolds with positive isotropic curvature to all dimensions $n \geq 5$ . This result also completes the classification of uniformly positive isotro…

The sharp isoperimetric inequality for varifolds in codimension two

Raphael Tsiamis

We prove a Michael-Simon inequality for a class of varifolds in Euclidean space that includes all integral varifolds with locally bounded first variation of arbitrary dimension and…

The anisotropic Michael-Simon inequality

Benjy Firester, Raphael Tsiamis

We prove a Michael-Simon inequality for varifolds of every dimension and codimension with respect to anisotropic energies. In particular, this resolves the problem for every convex…

The anisotropic Michael-Simon inequality for surfaces in every codimension

Benjy Firester, Raphael Tsiamis

We prove a Michael-Simon inequality for $2$ -varifolds in $R^{N}$ , in arbitrary codimension, for anisotropies sufficiently close to the area functional. Building on the ideas…

Stable $s$ -minimal cones in $R^{3}$ are flat for $s$ close to zero

Raphael Tsiamis

We prove that stable nonlocal minimal cones in three dimensions are flat, for $s$ sufficiently close to zero. Our approach develops new structural properties of stable $s$ -minimal…

On Chern's conjecture for minimal submanifolds of the sphere

Benjy Firester, Raphael Tsiamis

A well-known conjecture of Chern, do Carmo, and Kobayashi asserts that, for $n, m \geq 1$ , the scalar curvature of a closed, minimally immersed $n$ -submanifold of $S^{n + m}$ …

Sharp systolic inequalities for Kähler manifolds

Raphael Tsiamis

We establish sharp inequalities for two-dimensional systolic invariants of metrics with positive scalar curvature: the $2$ -systole and the spherical $2$ -systole of compact Kähler m…

Mean curvature flows with prescribed singular sets

Raphael Tsiamis

For every closed set $K \subset R^{n}$ and every $m \geq 2$ , we construct a mean-convex ancient solution to mean curvature flow of hypersurfaces in $R^{m + n}$ , with…

Topology of minimal surfaces in the sphere from capillarity

Benjy Firester, Raphael Tsiamis

We present a general construction of embedded minimal and constant mean curvature surfaces in $S^{n}$ and one-phase free boundaries joined by a smooth interpolation by capil…

New minimal surfaces in the sphere from capillary minimal cones

Benjy Firester, Raphael Tsiamis

For every $p, q \geq 1$ , we construct minimal embeddings of $S^{p} \times S^{q} \times S^{1}$ in $S^{p + q + 2}$ by doubling the links of free-boundary…

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…
