L^q-solutions to the Cosserat spectrum in bounded and exterior domains

If G ⊂ Rⁿ is a bounded or an exterior domain with sufficiently smooth boundary then for the eigenvalue problem
Δu = λ∇ div u,  u|_∂G = 0
λ = 1 is an eigenvalue of infinite multiplicity and λ = 2 is an accumulation point of eigenvalues of finite multiplicity...
