AI 中文摘要
本文证明了翻转和除子收缩保持凯勒条件(针对带有$B+\beta_X$大的强$\boldsymbol{\rm Q}$-因子紧凯勒广义klt对),给出了藤木类$\boldsymbol{\rm C}$簇为凯勒的判别准则,还证明了广义klt对存在小$\boldsymbol{\rm Q}$-因子分解及广义对的dlt修正。
英文摘要
In this article, we show that flips and divisorial contractions preserve the Kähler condition (for strongly $\mathbb{Q}$-factorial compact Kähler generalized klt pairs with $B+β_X$ big), and we give a criterion for varieties in Fujiki's class $\mathcal C$ to be Kähler. We also prove the existence of small $\mathbb Q$-factorializations for generalized klt pairs and of dlt modifications for generalized pairs.
