Gradient estimates for a weighted parabolic equation under geometric flow

Abstract: Let (M n , g, e −φ dv) be a weighted Riemannian manifold evolving by geometric flow ∂g ∂t = 2h(t), ∂φ ∂t = ∆φ. In this paper, we obtain a series of space-time gradient estimates for positive solutions of a parabolic partial equationon a weighted Riemannian manifold under geometric flow. By integrating the gradient estimates, we find the corresponding Harnack inequalities.

“…Along different geometric flows, he also obtained Li-Yau-type estimates and Perelman-type differential Harnack inequalities. Differential Harnack estimates and gradient estimates were studied in [6,[17][18][19][20][21][22][23][24][25]. In recent studies, a group of researchers have made advancements in the field of special submanifolds within various spaces [26][27][28][29][30][31][32][33][34][35][36][37][38].…”
