On the invariance of irregular Hodge numbers under crepant birational equivalences
Yichen Qin
The Batyrev--Kontsevich theorem asserts that birational Calabi--Yau varieties have the same Hodge numbers. In this article, we prove an analogue for Landau--Ginzburg models …

Classical and irregular Hodge numbers
Yichen Qin, Dingxin Zhang
Let be a smooth quasi-projective complex variety with a regular function . The twisted de Rham cohomology groups carry the decreasing irre…
