摘要

M1M_1M2M_2 为两个 K"ahler 流形。若 M1M_1M2M_2 共享一个非平凡 K"ahler 子流形 SS,即存在两个全纯等距浸入(K"ahler 浸入)h1:S>M1h_1: S -> M_1h2:S>M2h_2: S -> M_2,则称 M1M_1M2M_2 为“亲属”。本文证明,具有齐性 K"ahler 度量的有界齐性域与射影 K"ahler 流形(即赋予 Fubini-Study 度量限制的射影流形)不是亲属。我们的结果推广了 A. J. Di Scala 和 A. Loi 在"K"ahler manifolds and their relatives" (Ann. Sc. Norm. Super. Pisa Cl. Sci. (5) 9 3 (2010), 495-501) 中针对 Bergman 度量所得的结果。
