Abstract

Let (M,g) be any closed Riemannianan manifold and (N,h) be a Riemannian\nmanifold of constant positive scalar curvature. We prove that the Yamabe\nequation on the Riemannian product (M\× N , g + \δ h) has at least\nCat(M) +1 solutions for \δ small enough, where Cat(M) denotes the\nLusternik-Schnirelmann-category of M. Cat(M) of the solutions obtained have\nenergy arbitrarily close to the minimum.\n
