摘要
Let lambda(1) be the first nontrivial eigenvalue of the Laplacian on a compact surface without boundary. We show that lambda(1) = 2 on compact embedded minimal surfaces in S-3 which are invariant under a finite group of reflections-and whose fundamental piece is simply connected and has less than six edges, In particular lambda(1) = 2 on compact embedded minimal surfaces in S-3 that are constructed by Lawson and by Karcher-Pinkall-Sterling.
