# 含权双调和椭圆型问题的特征值不等式Eigenvalue Inequality for a Weighted Biharmonic Elliptic Problem

Abstract: In this paper, we study the relation between the first and the second eigenvalue of a weighted biharmonic elliptic problem with Dirichlet boundary. By some variational technique we obtain the corresponding inequality, and some evaluations are put forward in low dimension space.
