The Fr\"olicher spectral sequence can be arbitrarily non degenerate

Algebraic Geometry 2013-11-22 v3 Differential Geometry

Abstract

The Fr\"olicher spectral sequence of a compact complex manifold XX measures the difference between Dolbeault cohomology and de Rham cohomology. We construct for n2n\geq 2 nilmanifolds with left-invariant complex structure XnX_n such that the nn-th differential dnd_n does not vanish. This replaces an earlier incorrect example by the second author.

5 pages, Lemma 2 in v2 incorrect. v3: First author added, new example constructed (by the same method). Shorter Erratum will appear in Math. Ann. as well
