Universal meager $F_\sigma$-sets in locally compact manifolds

Geometric Topology 2013-05-28 v2 General Topology

Abstract

In each manifold MM modeled on a finite or infinite dimensional cube [0,1]n[0,1]^n we construct a meager FσF_\sigma-subset XMX\subset M which is universal meager in the sense that for each meager subset AMA\subset M there is a homeomorphism h:MMh:M\to M such that h(A)Xh(A)\subset X. We also prove that any two universal meager FσF_\sigma-sets in MM are ambiently homeomorphic.
