Rigidity of kappa-noncollapsed steady Kahler-Ricci solitons

摘要

In this paper, we show that any n-dimensional kappa-noncolla-psed steady (gradient) Kahler-Ricci soliton with nonnegative bisectional curvature must be flat. The result is an improvement to our former work in Deng and Zhu (Trans Am Math Soc 370(4):2855-2877, 2018).
