A gap theorem on complete shrinking gradient Ricci solitons
Shijin Zhang
In this short note, using Günther's volume comparison theorem and Yokota's gap theorem on complete shrinking gradient Ricci solitons, we prove that for any complete shrinking gradi…

Gradient Kähler-Ricci solitons with nonnegative orthogonal bisectional curvature
Shijin Zhang
In this paper, we prove that any complete shrinking gradient Kähler-Ricci solitons with positive orthogonal bisectional curvature must be compact. We also obtain a classification o…

Remarks on shrinking gradient Kähler-Ricci solitons with positive bisectional curvature
Guoqiang Wu, Shijin Zhang
In this short note, using an argument by Munteanu and Wang, we provide an alternative proof of the fact first obtained by Lei Ni that shrinking gradient Kähler-Ricci solitons with…
