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…

Singularity models for the Bernoulli free boundary problem from isoparametric hypersurfaces

Benjy Firester, Raphael Tsiamis, Zihui Zhao

We develop a general construction of homogeneous solutions to the Bernoulli free boundary problem, as well as general extremal domains on the sphere, from isoparametric foliations…

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…

Regularity of varifolds with bounded anisotropic first variation

Antonio De Rosa, Benjy Firester, Raphael Tsiamis

We prove an $ε$ -regularity theorem for $m$ -varifolds with mean curvature in $L^{p}$ , $p > m$ , with respect to an anisotropic integrand satisfying a Michael-Simon inequality a…

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…

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 $7$ 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 $- n (n - 1)$ . Gromov proposed a conjecture relating the infimum of the mean curvature of such a fill-in to the…

Uniqueness of Cylindrical Tangent Cones $C_{p, q} \times R$

Benjy Firester, Raphael Tsiamis, Yipeng Wang

We show the uniqueness of the cylindrical tangent cone $C (S^{2} \times S^{4}) \times R$ for area-minimizing hypersurfaces in $R^{9}$ , completing the u…

Classification of Semigraphical Translators

Francisco Martín, Mariel Sáez, Raphael Tsiamis +1

We complete the classification of semigraphical translators for mean curvature flow in $R^{3}$ that was initiated by Hoffman-Martín-White. Specifically, we show that there i…

Cohomogeneity two Ricci solitons with sub-Euclidean volume

Benjy Firester, Raphael Tsiamis

We introduce new families of four-dimensional Ricci solitons of cohomogeneity two with volume collapsing ends. In a local presentation of the metric conformal to a product, we redu…

Eigenvalue estimates on shrinkers

S. Brendle, R. Tsiamis

We prove an eigenvalue estimate which holds on every properly embedded shrinker for mean curvature flow. This generalizes earlier work of Ding and Xin to the noncompact case.

We prove a conjecture by Hoffman, White, and the first author regarding the uniqueness of pitchfork and helicoid translators of the mean curvature flow in $R^{3}$ . We employ…
