A Hodge-type decomposition of holomorphic Poisson cohomology on nilmanifolds

Abstract: A cohomology theory associated to a holomorphic Poisson structure is the hypercohomology of a bi-complex where one of the two operators is the classical ∂-operator, while the other operator is the adjoint action of the Poisson bivector with respect to the Schouten-Nijenhuis bracket. The first page of the associated spectral sequence is the Dolbeault cohomology with coefficients in the sheaf of germs of holomorphic polyvector fields. In this note, the authors investigate the conditions for which this spectral s… Show more

“…Based on such foundation, the author and his collaborators recently identify when the spectral sequence degenerates on the first page if the complex structure is abelian and the underlying nilmanifold is 2-steps [48] [49]. It enables an effective computation of holomorphic Poisson cohomology.…”

“…where the differential operator b π (−) = [π, −] is the adjoint action of π with respect to the Schouten bracket; see [25,23]. This cohomology has been widely studied; see, for example, [20,12,10,7,27,28,19] and references therein. Dually, from a homological point of view, we have the so called holomorphic Koszul-Brylinski complex:…”
