本文研究了任意阶聚拉普拉斯算子的狄利克雷特征值问题和拉普拉斯算子的二次多项式算子。我们给出了它们的前 k 个特征值之和的下界的一些估计。
In this paper, we investigate the Dirichlet eigenvalue problems of the poly-Laplacian with any order and the quadratic polynomial operator of the Laplacian. We give some estimates for lower bounds of the sums of their first k eigenvalues.
