Gradient estimates for some evolution equations on complete smooth metric measure spaces

Nguyen Thac Dung, Kieu Thi Thuy Linh, Ninh Van Thu

In this paper, we consider the following general evolution equation $u_{t} = Δ_{f} u + a u lo g^{α} u + b u$ on smooth metric measure spaces $(M^{n}, g, e^{- f} d v)$ . We give a local gradient estim…

A generalization of almost Schur lemma on CR manifolds

Jui-Tang Chen, Nguyen Thac Dung, Chin-Tung Wu

In this paper, we study a general almost Schur Lemma on pseudo-Hermitian (2n+1)-manifolds $(M, J, θ)$ for $n \geq 2$ . When the equality of almost Schur inequality holds, we derive the…
