关于Neumann Laplacian下特征值的Ashbaugh和Benguria猜想
On a Conjecture of Ashbaugh and Benguria about Lower Eigenvalues of the Neumann Laplacian
摘要:
本文证明了欧几里得空间或双曲空间有界域上自由膜问题低阶特征值的一个等周不等式,它加强了著名的Szegö-Weinberger不等式,并强有力地支持了Ashbaugh-Benguria的一个重要猜想.
英文摘要:
In this paper, we prove an isoperimetric inequality for lower order eigenvalues of the free membrane problem on bounded domains of a Euclidean space or a hyperbolic space which strengthens the well-known Szegö-Weinberger inequality and supports strongly an important conjecture of Ashbaugh-Benguria.
