On small covers over Bier spheres
Suyoung Choi, Younghan Yoon, Seonghyeon Yu
The paper classifies real toric manifolds (small covers) over Bier spheres that arise from the skeleta of a simplex, determines their homeomorphism types for certain skeleta, and c…

Full subcomplexes of Bier spheres
Suyoung Choi, Younghan Yoon, Seonghyeon Yu
Full subcomplexes of a simplicial complex encode essential structure for understanding the complex itself. For a simplicial complex , possibly with a ghost vertex, the Bier sphe…
