ON THE TENSOR FORMULATION OF EFFECTIVE VECTOR LAGRANGIANS AND DUALITYTRANSFORMATIONS

Using two different methods inspired by duality transformations we pre sent the equivalence between effective Lagrangians for massive vector mesons using a vector field and an antisymmetric tensor field. This co mpletes the list of explicit field transformations between the various effective Lagrangian methods to describe massive vector and axial vec tor mesons. Our method automatically generates the point-like terms ne eded for off-shell equivalence.
