Kähler-Ricci solitons with almost maximal symmetry
Ha Tuan Dung, Catherine Searle, Hung Tran
This paper studies a non-trivial gradient Kähler-Ricci soliton, of complex dimension , with an isometry group of dimension at least . We show that the isometry group acts…
On isometry groups of gradient Ricci solitons
Ha Tuan Dung, Hung Tran
We give a result estimating the dimension of the Lie algebra of Killing vector fields on an irreducible non-trivial gradient Ricci soliton. Then we study the structure of this mani…
Sharp gradient estimates on weighted manifolds with compact boundary
Ha Tuan Dung, Nguyen Thac Dung, Jia-Yong Wu
In this paper, we prove sharp gradient estimates for positive solutions to the weighted heat equation on smooth metric measure spaces with compact boundary. As an application, we p…
Rigidity and vanishing theorems for complete translating solitons
Ha Tuan Dung, Nguyen Thac Dung, Tran Quang Huy
In this paper, we prove some rigidity theorems for complete translating solitons. Assume that the -norm of the trace-free second fundamental form is finite, for some $q\in\mat…
Sharp gradient estimates for a heat equation in Riemannian manifolds
Ha Tuan Dung, Nguyen Thac Dung
In this paper, we prove sharp gradient estimates for a positive solution to the heat equation in complete noncompact Riemannian manifolds. As its application, we…
