Detecting cohomology classes for the proper LS category. The case of semistable 3-manifolds

  • MANUEL CÁRDENAS (a1), FRANCISCO F. LASHERAS (a1) and ANTONIO QUINTERO (a1)
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.
