Homology growth, hyperbolization, and fibering
Title: Homology growth, hyperbolization, and fibering
Speaker: Kevin Schreve (Louisiana State University)
Abstract: I will talk about joint work with Grigori Avramidi and Boris Okun where we construct closed, aspherical 7-manifolds with word hyperbolic, special fundamental group that do not virtually fiber over the circle. The obstruction to fibering is linear F_p-homology growth in residual.towers of regular finite covers for an odd prime p. In previous work, we constructed locally CAT(0) examples, and I will describe what needs to be done to “hyperbolize” the construction.
