Gap theorems for compact gradient Sasaki–Ricci solitons
Keyword(s):
In this paper, by using estimates for the transverse Ricci curvature in terms of the Sasaki–Futaki invariant, we shall give some gap theorems for compact gradient Sasaki–Ricci solitons by showing some necessary and sufficient conditions for the solitons to be Sasaki–Einstein. Our results may be regarded as a Sasaki geometry version of recent works by Li and Fernández-López and García-Río.
