In this paper, we consider eigenvalues of the Dirichlet biharmonic operator on a bounded domain in a hyperbolic space. We obtain universal bounds on the (k + 1)th eigenvalue in terms of the first kth eigenvalues independent of the domains. 相似文献

Let Ω be a connected bounded domain in Rn. Denote by λi the i-th eigenvalue of the Laplacian operator with any order p:{0(-△)pu =λu u =■u/→■n =···=■→■np-1 p-u1=0 in Ω,on ■Ω.In this article, we give some expressions for upper bound of the (k + 1)-th eigenvalue λk+1 in terms of the first k eigenvalues. 相似文献

对四元K(a)hler流形中的浸入曲面引入了K(a)hler角的概念,同时讨论K(a)hler角是常数的情形.主要结果是:若x:M→N(c)是具有常数Q-截面曲率c的实四维四元空间形式N(c)中具有常数K(a)hler角θ(sinθ≠0)的等距浸入曲面,则必有c=0. 相似文献
