Classification of Q-trivial Bott manifolds
Suyoung Choi, Mikiya Masuda
A Bott manifold is a closed smooth manifold obtained as the total space of an iterated $\C P^1$-bundle starting with a point, where each $\C P^1$-bundle is the projectivization of…
Strong cohomological rigidity of a product of projective spaces
Suyoung Choi, Dong Youp Suh
We prove that for a toric manifold , any graded ring isomorphism $H^\ast(M) \to H^\ast(\prod_{i=1}^{m}\CP^{n_i})$ is induced by a diffeomorphism $\prod_{i=1}^m \CP^{n_i} \to M$.
Properties of Bott manifolds and cohomological rigidity
Suyoung Choi, Dong Youp Suh
The cohomological rigidity problem for toric manifolds asks whether the cohomology ring of a toric manifold determines the topological type of the manifold. In this paper, we consi…
Topological classification of torus manifolds which have codimension one extended actions
Suyoung Choi, Shintarô Kuroki
A toric manifold is a compact non-singular toric variety equipped with a natural half-dimensional compact torus action. A torus manifold is an oriented, closed, smooth manifold of…
