关于紧致复流形上同调不变量的线性组合

On linear combinations of cohomological invariants of compact complex manifolds

Jonas Stelzig

摘要:

证明了紧致复流形的Hodge数、Betti数和Chern数之间不存在不可预料的泛整线性关系和同余关系,并确定了这类数的双半纯或拓扑不变量的线性组合.这推广了Kotschick和Schreieder在Kähler情况下的结果。然后,我们开发了一个框架,以解决更一般的问题,同时考虑到“所有”上同调不变量(例如,维度的较高页的Frölicher谱序列,Bott-Chern和Aeppli上同调)。这使我们能够将一般问题简化为具体的作图题。我们在许多情况下解决这些问题。特别是,我们获得了完整的答案,普遍的关系和双半纯不变量在低维的一般性问题。

英文摘要:

We prove that there are no unexpected universal integral linear relations and congruences between Hodge, Betti and Chern numbers of compact complex manifolds and determine the linear combinations of such numbers which are bimeromorphic or topological invariants. This extends results in the Kähler case by Kotschick and Schreieder. We then develop a framework to tackle the more general questions taking into account `all' cohomological invariants (e.g. the dimensions of the higher pages of the Frölicher spectral sequence, Bott-Chern and Aeppli cohomology). This allows us to reduce the general questions to specific construction problems. We solve these problems in many cases. In particular, we obtain full answers to the general questions concerning universal relations and bimeromorphic invariants in low dimensions.
