摘要: 首先, 用散度定理和几何分析的方法研究紧致η-Ricci-Bourguignon孤立子的刚性问题, 得到了关于孤立子的势向量场和η的对偶向量场的两个关键积分公式. 其次, 在不同的积分条件下得到了该孤立子的刚性结果, 即证明了该孤立子或是η-Einstein流形或是Einstein流形.

Abstract: Firstly, by using  the divergence theorem and  geometric analysis methods, we  studied the rigidity problem of compact η-Ricci-Bourguignon solitons, and obtained two key integral formulas for  the potential vector field of the soliton and the dual vector field of η. Secondly, under different integral conditions, we obtain rigidity results of the soliton, which  proves that the soliton is either an η-Einstein manifold or an Einstein manifold.

Key words: η-Ricci-Bourguignon soliton, Einstein manifold, Killing vector field, dual vector field
