WebJun 5, 2024 · Show that there are natural maps. H B C p, q ( X) → H p, q ( X) and H B C p, q → H p + q ( X, C). This is also part of an exercise in Daniel Huybrechts' "Complex Geometry: An Introduction" (2.6.7) and I already made myself clear that the definition of the Bott-Chern cohomology makes sense. So does someone know a proof of this statement? WebAug 1, 2024 · The Bott-Chern cohomology are important invariants of complex manifolds [10]. It has been studied by many authors in recent years [1], [7], [6], [4], [8], [2]. For example, Schweitzer studied the Hodge theory for Bott-Chern cohomology and gave a hypercohomology interpretation to it [21].
