Integral bases for the second degree cohomology of 4-dimensional toric orbifolds

Tseleung So, Jongbaek Song

We study toric orbifolds of real dimension four with vanishing odd-degree cohomology and obtain a basis for its degree-two equivariant cohomology with integral coefficients by iden…

Cohomology bases of toric surfaces

Xin Fu, Tseleung So, Jongbaek Song

Given a compact toric surface, the multiplication of its rational cohomology can be described in terms of the intersection products of Weil divisors, or in terms of the cup product…

Homotopy rigidity for quasitoric manifolds over a product of -simplices

Xin Fu, Tseleung So, Jongbaek Song +1

For a fixed integer , we show that two quasitoric manifolds over a product of -simplices are homotopy equivalent after appropriate localization, provided that their int…

Toric surfaces with symmetries by reflections

Jongbaek Song

Let be a reflection group in a plane and a rational polygon that is invariant under the -action. The action of on induces a -action on the toric variety

Conic decomposition of a toric variety and its application to cohomology

Seonjeong Park, Jongbaek Song

We introduce the notion of a \emph{conic sequence} of a convex polytope. It is a way of building up a polytope starting from a vertex and attaching faces one by one with certain re…

The homotopy classification of four-dimensional toric orbifolds

Xin Fu, Tseleung So, Jongbaek Song

Let be a -dimensional toric orbifold. If has a non-trivial odd primary torsion, then we show that is homotopy equivalent to the wedge of a Moore space and a CW-…
