报告摘要:
Algebraically fibering group is an algebraic generalization of the fibered 3-manifold groups in higher dimensions. Jankiewicz-Norin-Wise showed that the fundamental groups of real moment-angled hyperbolic manifolds over the right-angled 24-cell and 120-cell are algebraic fibered. We further show that they are not FP2. In particular, those fiber-kernel groups are finite generated, but not finite presented. This is a joint work with Jiming Ma.
