چکیده
We show that the third eigenvalue of Neumann Laplacian in hyperbolic space is maximal for disjoint union two geodesic balls, among domains given volume. This extends a recent result by Bucur and Henrot Euclidean space, while providing new proof key step their argument

Monotonicity of the volume of four balls in hyperbolic space
Consider a collection of possibly overlapping balls in E d. Suppose the balls are rearranged so that the distances between the centers of the balls all increase or stay the same. Kneser and Poulsen independently conjectured in the 1950’s that the volume of the union must either increase or stay the same. Csikós proved that this is true in Euclidean space under a continuous expansion, and Connel...
متن کاملDirichlet-neumann Kernel for Hyperbolic-dissipative System in Half-space
The purpose of the present paper is to initiate a systematic study of the relation of the boundary values for hyperbolic-dissipative systems of partial differential equations. We introduce a general framework for explicitly deriving the boundary kernel for the Dirichlet-Neumann map. We first use the Laplace and Fourier transforms, and the stability consideration to derive the Master Relationshi...
متن کاملEigenvalue estimates for minimal surfaces in hyperbolic space
This paper gives an upper bound for the first eigenvalue of the universal cover of a complete, stable minimal surface in hyperbolic space, and a sharper one for least area disks.
متن کاملThe Hyperbolic Quadratic Eigenvalue Problem
The hyperbolic quadratic eigenvalue problem (HQEP) was shown to admit the Courant-Fischer type min-max principles in 1955 by Duffin and Cauchy type interlacing inequalities in 2010 by Veselić. It can be regarded as the closest analogue (among all kinds of quadratic eigenvalue problems) to the standard Hermitian eigenvalue problem (among all kinds of standard eigenvalue problems). In this paper,...
متن کاملLawson topology of the space of formal balls and the hyperbolic topology
Let (X, d) a metric space and BX = X × R denote the partially ordered set of (generalized) formal balls in X. We investigate the topological structures of BX, in particular the relations between the Lawson topology and the product topology. We show that the Lawson topology coincides with the product topology if (X, d) is a totally bounded metric space, and show examples of spaces for which the ...
