  • Abstract: Fibrations of hyperbolic 3-manifolds have attracted a lot of attention in the '80s, 90's and early 2000s, culminating in the Virtual Fibring Theorem of Agol in 2012. This raises the question of whether this phenomenon also occurs in higher dimensions. After a short survey about recent results, I will talk about recent progress on fibrations of Poincaré-duality groups, which is joint work with Sam Fisher and Dawid Kielak.
