A new graph invariant arises in toric topology
Suyoung Choi, Hanchul Park
In this paper, we introduce new combinatorial invariants of any finite simple graph, which arise in toric topology. We compute the -th (rational) Betti number and Euler characte…

Different moment-angle manifolds arising from two polytopes having the same bigraded Betti numbers
Suyoung Choi
Two simple polytopes of dimension 3 having the identical bigraded Betti numbers but non-isomorphic Tor-algebras are presented. These polytopes provide two homotopically different m…

Projective bundles over toric surfaces
Suyoung Choi, Seonjeong Park
Let be the Whitney sum of complex line bundles over a topological space . Then, the projectivization of is called a \emph{projective bundle} over . If is a…
