We provide a new construction that allows us to construct groups th at virtually fibre with finitely presented kernel. Obtaining finite presen tability is usually a big step forward\, since it allows to use homologica l methods (due to Kielak and Fisher) to leverage even stronger finiteness properties. However\, our technique is quite in dissonance with this\, so these particular examples do not seem to be upgradable in general. \n\nThi s is joint work with Matteo Migliorini and Andrew Ng.\n LOCATION:https://researchseminars.org/talk/GaTO/134/ END:VEVENT END:VCALENDAR
