本文计算了复维3的广义Calabi--Eckmann流形的整Bott--Chern上同调,证明非双全纯流形间该上同调环同构,并用特征映射区分不同上同调。
AI 中文摘要
我们计算了复维数为3的一类广义Calabi--Eckmann流形的整Bott--Chern上同调。尽管这些流形彼此不双全纯等价,我们证明它们的整Bott--Chern上同调环仍然是同构的。随后,通过上同调中的特征映射获得了上同调区分,该映射连接了奇异、Dolbeault和整Bott--Chern上同调。
英文摘要
We compute the integral Bott--Chern cohomology of a class of generalized Calabi--Eckmann manifolds of complex dimension \(3\). Although these manifolds are mutually non-biholomorphic, we show that their integral Bott--Chern cohomology rings are nevertheless isomorphic. A cohomological distinction is then obtained via a characteristic map in cohomology, connecting singular, Dolbeault, and integral Bott--Chern cohomologies.
