Abstract

Let (M,g) be a compact Riemannian manifold without boundary, with dim M ≤ 3, and π : ℝ → ℝ a continuous function which is sublinear at infinity. By various variational approaches, existence of multiple solutions of the eigenvalue problem -Δgω + α(σ)ω = K̄(λ, σ)π(ω), σ ∈ M, ω ∈ H21(M), is established for certain eigenvalues λ > 0, depending on further properties of π and on explicit forms of the function K̄. Here, Δg stands for the Laplace-Beltrami operator on (M, g), and α, K̄ are smooth positive functions. These multiplicity results are then applied to solve Emden-Fowler equations which involve sublinear terms at infinity.
