具位势的局部共形Kahler流形的LCK秩

LCK rank of locally conformally Kahler manifolds with potential

Liviu Ornea, Misha Verbitsky

摘要:

一个具有势的LCK流形是一个Kahler流形$X$的紧商,它具有一个正的Kahler势$f$,使得单值群通过全纯同素作用在$X$上,并将$f$乘以一个特征标。LCK秩是该字符的图像的秩,被认为是从单值群到实数的函数。证明了具有位势的LCK流形可以具有1到$b_1(M)$之间的任意秩.此外,具有真位势的LCK流形(秩为1的流形)是稠密的。最后一节给出了我们以前工作的两个勘误表。

英文摘要:

An LCK manifold with potential is a compact quotient of a Kahler manifold $X$ equipped with a positive Kahler potential $f$, such that the monodromy group acts on $X$ by holomorphic homotheties and multiplies $f$ by a character. The LCK rank is the rank of the image of this character, considered as a function from the monodromy group to real numbers. We prove that an LCK manifold with potential can have any rank between 1 and $b_1(M)$. Moreover, LCK manifolds with proper potential (ones with rank 1) are dense. Two errata to our previous work are given in the last Section.
