Nonlocal s-Minimal Surfaces and Lawson Cones

The nonlocal s-fractional minimal surface equation for Σ = ∂E where E is an open set in R N is given by H Σ s (p):= RN χE(x) − χEc(x ) dx = 0 for all p ∈ Σ. |x...

Compactness of scalar-flat conformal metrics on low-dimensional manifolds with constant mean curvature on boundary

We concern C2-compactness of the solution set of the boundary Yamabe problem on smooth compact Riemannian manifolds with boundary provided that their dimensions are 4, 5 or 6. By conducting a quantitative analysis...

Desingularization of Clifford torus and nonradial solutions to the Yamabe problem with maximal rank

Through desingularization of Clifford torus, we prove the existence of a sequence of nondegenerate (in the sense of Duyckaerts–Kenig–Merle ([8])) nodal nonradial solutions to the critical Yamabe problem −Δu=[Formula...

Sign-changing blowing-up solutions for the critical nonlinear heat equation
Let $\Omega$ be a smooth bounded domain in $\mathbb{R}^n$ and denote the regular part of the Green's function on $\Omega$ with Dirichlet boundary condition as $H(x,y)$. Assuming the integer $k_0$ is sufficiently large, $q \in...
