手术中K区的不变性
Invariance of Finiteness of K-area under Surgery
摘要：
K-面积是Gromov作为正数量曲率存在的障碍而引入的黎曼流形的不变量。然而，一般情况下，很难确定K-区域是否有限。尽管K区域的定义是相当自然的。在本文中，我们研究如何在手术下的不变量的变化。
英文摘要：
K-area is an invariant for Riemannian manifolds introduced by Gromov as an obstruction to the existence of positive scalar curvature. However in general it is difficult to determine whether K-area is finite or not. though the definition of K-area is quite natural. In this paper, we study how the invariant changes under surgery.
