On Dual Formulation of Gravity
Abstract
In this paper we consider a possibility to construct dual formulation of gravity where the main dynamical field is the Lorentz connection ω_μ^{ab} and not that of tetrad e_μ^a or metric g_μν. Our approach is based on the usual dualization procedure which uses first order parent Lagrangians but in (Anti) de Sitter space and not in the flat Minkowski one. It turns out that in d=3 dimensions such dual formulation is related with the so called exotic parity-violating interactions for massless spin-2 particles.
