Abstract
We find upper bounds for the Lusternik–Schnirelmann category of spaces with free fundamental groups. We prove, in particular, that if is a finite-dimensional CW complex with a free fundamental group, then . Our results specialize to resolve a question about the L–S category of manifolds posed by Dranishnikov, Katz and Rudyak.
