Abstract

Let be a compact constant mean curvature surface either in or . In this paper we prove that the stability index of is bounded from below by a linear function of the genus. As a by-product we obtain a comparison theorem between the spectrum of the Jacobi operator of and those of Hodge Laplacian of 1-forms on .
