The number of orientable small covers over cubes

Suyoung Choi

We count orientable small covers over cubes. We also get estimates for $O_{n} / R_{n}$ , where $O_{n}$ is the number of orientable small covers and $R_{n}$ is the number of all small covers o…

Topological classification of generalized Bott towers

Suyoung Choi, Mikiya Masuda, Dong Youp Suh

If $B$ is a toric manifold and $E$ is a Whitney sum of complex line bundles over $B$ , then the projectivization $P (E)$ of $E$ is again a toric manifold. Starting with $B$ as a poin…

Toric cohomological rigidity of simple convex polytopes

Suyoung Choi, Taras Panov, Dong Youp Suh

A simple convex polytope $P$ is \emph{cohomologically rigid} if its combinatorial structure is determined by the cohomology ring of a quasitoric manifold over $P$ . Not every $P$ ha…

The number of small covers over cubes

Suyoung Choi

In the present paper we find a bijection between the set of small covers over an $n$ -cube and the set of acyclic digraphs with $n$ labeled nodes. Using this, we give a formula of t…

Quasitoric manifolds over a product of simplices

Suyoung Choi, Mikiya Masuda, Dong Youp Suh

A quasitoric manifold (resp. a small cover) is a $2 n$ -dimensional (resp. an $n$ -dimensional) smooth closed manifold with an effective locally standard action of $(S^{1})^{n}$ (resp. $(…
