Abstract
This paper considers a compact Finsler manifold (Mn, F(t), m) evolving under the Finsler-Ricci flow and establishes global gradient estimates for positive solutions of the following nonlinear heat equation:
where Δm is the Finsler-Laplacian. As applications, several Harnack inequalities are obtained.
