WebBriefly, the Bott-Chern classes arise as follows. On a complex manifold the exterior derivative decomposes into a sum , and the smooth -forms decompose into a direct sum of -forms. Let be the space of smooth -forms on . Then the operator makes into a differential complex. Thus, the cohomology is defined. WebThe purpose of this paper is to study the bimeromorphic invariants of compact complex manifolds in terms of Bott–Chern cohomology. We prove a blow-up formula for Bott–Chern cohomology. As an application, we show that for compact complex threefolds the non-Kählerness degrees, introduced by Angella–Tomassini [Invent.
