Abstract
An effective lagrangian is constructed for the system of pions, ρ mesons and skyrmions in the light of a hidden local SU(2) symmetry in a non-linear sigma model. It describes vector dominance relations such as the KSRF relation, the ρ universality and the ρ-pole dominance in the photon coupling. It also satisfies all soft-pion threshold theorems.Keywords
