(**) (h)Vol(S, h) S 8π , where Vol(S, h) denotes the volume of S with respect to h. Equality in (*) or (**) holds if and only if h is a constant curvature metric. M. Berger [1] showed that (*) cannot be generalized for (S, h), m^>3. With respect to (**), M. Berger [1] posed a problem: Let I be a compact smooth manifold; then does there exist a constant k{M) depending only on M such that the first eigenvalue {h) of the Laplacian satisfies
