摘要

研究完备梯度收缩K?hler-Ricci孤立子, 在Bochner张量的4阶散度等于零的条件下 (即 $\text{div}^{4}(W)= $ $ \nabla_{\bar{k}}\nabla_{j}\nabla_{\bar{i}}\nabla_{l}W_{i\bar{j}k\bar{l}}=0$ ), 得到了其分类结果.

Abstract

In this paper, we study complete gradient shrinking K?hler-Ricci solitons with a vanishing fourth-order Bochner tensor (i.e. $\text{div}^{4}(W)=\nabla_{\bar{k}}\nabla_{j}\nabla_{\bar{i}}\nabla_{l}W_{i\bar{j}k\bar{l}}=0$ ), and obtain the corresponding classification results.

Key words： K?hler-Ricci soliton; Bochner tensor; harmonic Bochner tensor
