报告题目:Equivariant Bordism of 2-Torus Manifolds and Unitary Toric Manifolds
报告摘要:The equivariant bordism classification of manifolds with group actions is an essential subject in the study of transformation groups. In this talk, we will consider the actions of 2-torus group $\Z_2^n$ and torus group $T^n$. In detail we give a new description of the equivariant bordism groups $\mathcal{Z}_n(\Z_2^n)$ of 2-torus manifolds, and compute its dimensions(as a $\Z_2$-vector space). Furthermore, we give an analogue on the equivariant bordism of unitary toric manifolds。
