Detecting cohomology classes for the proper LS category. The case of semistable 3-manifolds†
Published online by Cambridge University Press: 21 December 2011
Abstract
We give sufficient conditions for the existence of detecting elements for the Lusternik–Schnirelmann category in proper homotopy. As an application we determine the proper LS category of some semistable one-ended open 3-manifolds.
