摘要
An abstract operator equation, Au = λBu, was considered where λ∈R is a spectral parameter and A,B are operators acting from a certain Banach space into its dual. As an example, weak solvability of the nonlinear eigenvalue problem in RN is provided: -div a(x,u, ▽u)+c(x,u,▽u) = λb(x,u)+g(λ,x,u), where the assumptions on a, b, c and g are specified.
