Extensions of maps to the projective plane

Jerzy Dydak and Michael Levin

Algebraic & Geometric Topology 5 (2005) 1711–1718

arXiv: math.GT/0410370

Abstract

It is proved that for a 3–dimensional compact metrizable space X the infinite real projective space P is an absolute extensor of X if and only if the real projective plane P2 is an absolute extensor of X (see Theorems 1.2 and 1.5).

Keywords
