These notes have their origin in a conjecture of J. Rauch. Let Ω be a domain in R and let V2 be the smallest positive eigenvalue of the Laplace operator in ઢે under homogeneous Neumann boundary conditions. Then, so the conjecture, the associated eigenfunction u2 should attain its maximum and minimum on the boundary an. More on the conjecture can be found in § 5.
