Suspension splittings of 5-dimensional Poincaré duality complexes and their applications

Steven Amelotte, Tyrone Cutler, Tseleung So

Let $X$ be a connected, orientable, 5-dimensional Poincaré duality complex with torsion-free $H_{1} (X; Z)$ . We show that $Σ X$ is homotopy equivalent to a wedge of recognisabl…

Weighted polyhedral products and Steenrod's problem

Tseleung So, Donald Stanley, Stephen Theriault

We construct a weighted version of polyhedral products and compute its cohomology in special cases. This is applied to resolve Steenrod's cohomology realization problem in a case r…

The integral cohomology rings of four-dimensional toric orbifolds

Xin Fu, Tseleung So, Jongbaek Song

Let $X (P, λ)$ be a 4-dimensional toric orbifold associated to a polygon $P$ and a characteristic function $λ$ . Assuming that $X (P, λ)$ is locally smooth over a vertex of $P$ , we dete…
