On the toric lifting properties for simplicial $3$ -spheres

Suyoung Choi, Yuanxin Guan, Hyeontae Jang +1

We study the lifting problem for mod $2$ characteristic maps over simplicial $3$ -spheres. Using a bad-block partition of the universal complex $X (Z_{2}^{4})$ , we prove an avoi…

Equivariant bordism classification of five-dimensional $(Z_{2})^{3}$ -manifolds with isolated fixed points

Yuanxin Guan, Zhi LÃ¼

Denote by $Z_{5} ((Z_{2})^{3})$ the group, which is also a vector space over $Z_{2}$ , generated by equivariant unoriented bordism classes of all five-dimensional…

Representation characterization of equivariant geometric bordism

Hao Li, Zhi LÃ¼, Bo Chen +2

Let $G_{k} = (Z_{2})^{k}$ . We establish a representation characterization determining when finitely many faithful $G_{k}$ -representations can serve as the fixed-point data of a smoot…
