Abstract:

In this paper, we study the Dirichlet eigenvalue problem of the weighted Laplace operator Lϕ on a bounded domain Ω with a smooth boundary in n-dimensional Euclidean space. Under the premise that the weighted function ϕ satisfies certain constraints, a universal inequality of the eigenvalue problem can be obtained by using the variational method and constructing the test function appropriately.

Key words: weighted Laplace operator, Dirichlet eigenvalue problem, Green formula
