Iwasawa manifold : ウィキペディア英語版 | Iwasawa manifold In mathematics, in the field of differential geometry, an Iwasawa manifold is a compact quotient of a 3-dimensional complex Heisenberg group by a cocompact, discrete subgroup. An Iwasawa manifold is a nilmanifold, of real dimension 6. Iwasawa manifolds give examples where the first two terms ''E''1 and ''E''2 of the Frölicher spectral sequence are not isomorphic. As a complex manifold, such an Iwasawa manifold is an important example of a compact complex manifold which does not admit any Kähler metric. == References ==
