文摘This paper deals with the gradient estimates of the Hamilton type for the positive solutions to the following nonlinear diffusion equation:on a complete noncompact Riemannian manifold with a Bakry-Emery Ricci curvature bounded below by -K (K 〉 0), where φ is a C2 function, a(x) and b(x) are C1 functions with certain conditions.
