In this paper, we are concerned with upper bounds of Eigen values on manifolds. Eigen values have many applications in geometry and in other fields of mathematics. We develop a universal approach to upper bounds on both continuous and discrete structures based upon certain properties of the corresponding heat kernel. we start with a well-defined Laplace operator Δ on functions on M so that Δ is a self-ad joint operator in L2(M, +) with a discrete spectrum and a distance function dist(x, y) on M.
