Abstract

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 Kahler 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 Frolicher 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.(c) 2022 Elsevier Inc. All rights reserved.
