摘要：

We prove that if Omega is an open bounded domain with smooth and connected boundary, for every p is an element of (1,+infinity) the first Dirichlet eigenvalue of the normalized p-Laplacian is simple in the sense that two positive eigenfunctions are necessarily multiple of each other. We also give a (nonoptimal) lower bound for the eigenvalue in terms of the measure of Omega, and we address the open problem of proving a Faber-Krahn-type inequality with balls as optimal domains.
