Popis:	Following [11], we say that metric compacta X and Y have unstable intersection in R n provided that each pair of maps f : X → R n and g : Y → R n may be uniformly e-approximated by maps f ′: X → R n and g ′: Y → R n with disjoint images for all e>0. We prove that this implies that dim X × Y n .
