In this paper, we consider the problem with the class of one-twist Bott manifolds to get an affirmative answer to the problem. We also generalize the result to quasitoric manifolds. In doing so, we show that the twist number of a Bott manifold is well-defined and is equal to the cohomological complexity of the cohomology ring of the manifold. We also show that any cohomology Bott manifold is homeomorphic to a Bott manifold. All these results are also generalized to the case with $\\mathbb Z_{(2)}$-coefficients, where $\\mathbb Z_{(2)}$ is the localized ring at 2.", "revisions": [ { "version": "v1", "updated": "2009-12-16T04:28:20.000Z" } ], "analyses": { "subjects": [ "57S25", "22F30" ], "keywords": [ "properties", "toric manifolds asks", "cohomology bott manifold", "one-twist bott manifolds", "toric manifold determines" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0912.3054C" } } }
