When the Riemannian metric evolves under the Ricci flow, we investigate parabolic gradient estimates (Li–Yau’s type and J. Li’s type) for positive solutions to the non- |∇u| linear parabolic equation ( − ∂ )u = (p + 1) + qu on the underlying manifold. Based on these gradient estimates, we derive associated Harnack inequalities, respec- tively.

More- over, they deduced Harnack inequalities. The Harnack inequality also applied to the Ricci flow by Hamilton (1993) and played an important role in solving the Poincaré conjecture Cao and Zhu (2006); Perelman (Perelman). After the fundamental work of Li and Yau (1986), the investigation of Li–Yau estimates for general parabolic partial differential equations of second order has drawn much attentions. To name a few, Yang (2008) proved the Li–Yau estimate for the equation on a Riemannian manifold of ∂ u = u + au ln u + bu with a, b ∈ R, which was
