About Bounds for Eigenvalues of the Laplacian with Density
Let denote a compact, connected Riemannian manifold of dimension ∈ ℕ. We assume that has a smooth and connected boundary. Denote by and d, respectively, the Riemannian metric on and the associated volume element. Let Δ be the Laplace operator on equipped with the weighted volume form d:= e⁻ʰd....

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Let denote a compact, connected Riemannian manifold of dimension ∈ ℕ. We assume that has a smooth and connected boundary. Denote by and d, respectively, the Riemannian metric on and the associated volume element. Let Δ be the Laplace operator on equipped with the weighted volume form d:= e⁻ʰd. We are interested in the operator Lₕ⋅ :=e⁻ʰ⁽ᵅ⁻¹⁾(Δ⋅+α(∇h, ∇⋅)), where α > 1 and ∈ ²() are given. The main result in this paper states the existence of upper bounds for the eigenvalues of the weighted Laplacian Lₕ with the Neumann boundary condition if the boundary is non-empty.
