Stability results for the N-dimensional Schiffer conjecture via a perturbation method

Given a eigenvalue μ2 0m of -Δ in the unit ball B1, with Neumann boundary conditions, we prove that there exists a class D of C0,1-domains, depending on μ0m, such that if u is a no trivial solution to the following problem Δu + μu = 0 in Ω, u = 0 on ∂Ω, and ∫∂Ω∂nu = 0, with Ω ∈ D, and μ = μ20 m +o(1...
