Strong Cohomological rigidity of Bott manifolds
Suyoung Choi, Taekgyu Hwang, Hyeontae Jang
We show that the strong cohomological rigidity conjecture for Bott manifolds is true. Namely, any graded cohomology ring isomorphism between two Bott manifolds is induced by a diff…
Gromov width of symplectic toric manifolds associated with graphs
Suyoung Choi, Taekgyu Hwang
We give an explicit formula for the Gromov width for a class of symplectic toric manifolds constructed from simple graphs. As a corollary, we show a version of non-squeezing theore…
On the KO-groups of toric manifolds
Li Cai, Suyoung Choi, Hanchul Park
In this paper we consider the real topological K-groups of a toric manifold M, which turns out to be closely related to the topology of the small cover MR, the fixed points under t…
Multiplication structure of the cohomology ring of real toric spaces
Suyoung Choi, Hanchul Park
A real toric space is a topological space which admits a well-behaved -action. Real moment-angle complexes and real toric varieties are typical examples of real tor…
Example of C-rigid polytopes which are not B-rigid
Suyoung Choi, Kyoungsuk Park
A simple polytope is said to be \emph{B-rigid} if its combinatorial structure is characterized by its Tor-algebra, and is said to be \emph{C-rigid} if its combinatorial structu…
Small covers over wedges of polygons
Suyoung Choi, Hanchul Park
A small cover is a closed smooth manifold of dimension having a locally standard -action whose orbit space is isomorphic to a simple polytope. A typical example…
