我们在光滑复射影簇之间构造具有奇异纤维但拓扑上看似光滑的态射,以此对四个猜想和问题给出否定答案:Fernández~de~Bobadilla与Kollár的光滑性猜想、Kollár与Pardon关于万有覆叠的问题、Kotschick的1-形式猜想,以及Schreieder关于Aomoto复形的猜想。
英文摘要
We construct morphisms between smooth complex projective varieties that have singular fibers, but look topologically smooth. We use this to give negative answers to the following four conjectures and questions: the smoothness conjecture of Fernández~de~Bobadilla and Kollár, a question of Kollár and Pardon on universal covers, Kotschick's conjecture on 1-forms, and a conjecture of Schreieder on Aomoto complexes. Version 2 is a revised version of sections 1--6 of the original, no change in the results. A substantially expanded version of sections 7--8 of the original will be posted separately.
