An aspherical 5-manifold with perfect fundamental group
Abstract: We construct aspherical closed orientable 5-manifolds with perfect fundamental group. This completes part of our study (with D.H.Kochloukova and I.Lima) of $PD_n$-groups with pro-$p$ completion a pro-$p$ Poincar\'e duality group of dimension $\leq{n-2}$. We also consider the question of whether there are any examples with "dimension drop" 1.
