Given any closed Riemannian manifold (M, g) we use the Lyapunov-Schmidt finitedimensional reduction method to prove multiplicity results for positive solutions of a subcritical Yamabe type equation on (M, g). If (N, h) is a closed Riemannian manifold of constant positive scalar curvature our result gives multiplicity results for the Yamabe equation on the Riemannian product (M × N, g + ε 2 h), for ε > 0 small.
