## Let be a bounded domain in N and let m be a T -periodic function such that its restriction to Γ— 0 T belongs to L s 0 T L v for some v > N 2 and s > 2v 2v-N , with v > 1 and s β‰₯ 2. We give necessary and sufficient conditions on m for the existence, uniqueness, and simplicity of the principal eig
