Abstract: In this paper, we study the Dirichlet eigenvalue problem of the weighted Laplace operator $\mathbb {L}_\phi$ on a bounded domain $\Omega$ with a smooth boundary in $n$-dimensional Euclidean space. Under the premise that the weighted function $\phi$ 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
