Spectral and Geometric Stability for the Reciprocal Sum of Neumann Eigenvalues
Yulong Li, Zuoqin Wang
We establish quantitative stability for the reciprocal-sum isoperimetric inequality for the first nonzero Neumann eigenvalues, recently proved by He, Li, and Tang. We prove tha…

Bessel functions and Weyl's law for balls and spherical shells
Jingwei Guo, Tao Jiang, Zuoqin Wang +1
The purpose of this paper is twofold. One is to investigate the properties of the zeros of cross-products of Bessel functions or derivatives of ultraspherical Bessel functions, as…
