In this paper, we derive Li-Yau gradient estimates for the positive solution of a nonlinear parabolic equation , where is a function and , are constants, on a complete manifold (,) with bounded below Ricci curvature. The results generalize classical Li-Yau gradient estimates and some recent works on this direction.
