摘要

假设 (M4,g,f) 是一个完全收缩梯度利玛窦孤子。我们给出了一个孤子紧凑的充分条件，概括了 Munteanu-Wang [17] 以前的结果。作为应用，我们给出了 (M4,g,f) 在一些自然条件下的分类。

When are shrinking gradient Ricci soliton compact

Suppose $(M^{4}, g, f)$ is a complete shrinking gradient Ricci soliton. We give a sufficient condition for a soliton to be compact, generalizing previous result of Munteanu-Wang [17]. As an application, we give a classification of $(M^{4}, g, f)$ under some natural conditions.
