Abstract
Let f:XâY be a perfect map between finite-dimensional metrizable spaces and p⩾1. It is shown that the space Câ(X,Rp) of all bounded maps from X into Rp with the source limitation topology contains a dense Gδ-subset consisting of f-regularly branched maps. Here, a map g:XâRp is f-regularly branched if, for every n⩾1, the dimension of the set {zâYÃRp:|(fÃg)â1(z)|⩾n} is ⩽nâ
(dimf+dimY)â(nâ1)â
(p+dimY). This is a parametric version of the Hurewicz theorem on regularly branched maps.
