Conformal Ricci Curvature and Spectral Estimates
Xiaoshang Jin
We derive optimized upper bounds for the first Dirichlet eigenvalue of a bounded domain under lower bounds for the conformal Ricci tensor of Shen and Ye. The method also yields sha…

Xiaoshang Jin, Yao Wan, Jie Xiao
This paper establishes sharp upper bounds for -capacities in the hyperbolic space through hyperbolic quermassintegrals and effective c…
Capacities-to-masses for Laplace-Beltrami operators on complete Riemannian manifolds
Xiaoshang Jin, Jie Xiao
This paper presents an innovative approach to the capacities-to-masses for the Laplace-Beltrami operators on the complete Riemannian manifolds, unexpectedly solving the open proble…
Heat dispersion laws in smooth compact manifolds
Xiaoshang Jin, Jie Xiao
Given a Lipschitz conductor in the smooth compact Riemannian -manifold , such a half generic heat dispersion law $$ {\rm H^d}_{p,\varPhi,\varPsi}(K,M)=2^{-1} {\r…
Essential -capacity-volume estimates for rotationally symmetric manifolds
Xiaoshang Jin, Jie Xiao
Given , this article presents the novel basic volumetric estimates for the relative -capacities with their applications to finding not only the sharp weak $(p,q…
Sharply estimating hyperbolic capacities
Xiaoshang Jin, Jie Xiao
This paper is devoted to establishing four types of sharp capacitary inequalities within the hyperbolic space as detailed in Theorems 2.1-3.1-4.1-5.1.
