Sharp ratios for low-index Neumann eigenvalues on convex domains

Quanyu Tang, Haiqi Zhang

Let $Ω \subset R^{N}$ be a bounded open convex set, and let $0 = μ_{0} (Ω) < μ_{1} (Ω) \leq μ_{2} (Ω) \leq \dots$ be the Neumann eigenvalues of the Laplacian, repeated according to multiplicit…

The Ashbaugh--Benguria reciprocal-gap conjecture for Dirichlet eigenvalues

Yanyang Li, Quanyu Tang, Haiqi Zhang

We prove the Ashbaugh--Benguria reciprocal-gap conjecture for the Dirichlet Laplacian in every dimension $N \geq 2$ . Specifically, if $Ω \subset R^{N}$ is a bounded domain and $$…

A sharp fixed-volume product inequality for the first $N$ nonzero Steklov eigenvalues

Haiqi Zhang, Quanyu Tang, Yanyang Li

We prove a sharp fixed-volume product inequality for the first $N$ nonzero Steklov eigenvalues of bounded Lipschitz domains in $R^{N}$ . More precisely, if $N \geq 2$ and $Ω\subs…
