Well-posedness for the mean curvature flow on the half-space and on bounded domains

Ke Chen, Ruilin Hu, Quoc-Hung Nguyen

We study graphical mean curvature flow in arbitrary codimension over the half-space and over smooth bounded domains, subject to homogeneous Dirichlet boundary conditions. At the sc…

Schauder-type Estimates and Log-Critical Well-posedness for the Two-Phase Muskat Problem with Surface Tension

Ke Chen, Ruilin Hu, Quoc-Hung Nguyen

We prove short-time well-posedness for the Muskat problem with surface tension in the full two-phase setting, allowing different viscosities, arbitrary density contrast, and rigid…

Schauder-type Estimates and Well-posedness for Nonlocal Quasilinear Evolution Equations in Fluid Dynamics

Ke Chen, Ruilin Hu, Quoc-Hung Nguyen

We establish Schauder-type estimates for linear parabolic systems driven by variable-coefficient nonlocal pseudo-differential operators of order . These estimates are formulat…

Scaling-Critical Theory for the Boltzmann and Landau Equations

Ke Chen, Quoc-Hung Nguyen, Tong Yang

For sufficiently small initial perturbations in a localized, weighted, anisotropic Riesz-potential norm, we prove global well-posedness near a Maxwellian in the whole space. This c…

Well-posedness of the Fractional Fokker-Planck Equation

Ke Chen, Ruilin Hu, Quoc-Hung Nguyen

In this paper, we employ a Schauder-type estimate method, as developed in \cite{CHN}, to establish critical well-posedness result for the Fractional Fokker-Planck Equation. This eq…

The Muskat problem with a large slope

Yiran Xu, Stephen Cameron, Ke Chen +2

In this paper, we establish local well-posedness results for the Muskat equation in any dimension using modulus of continuity techniques. By introducing a novel quantity \(β_σ(f_…
