This is analogous to the connection representation in which the ``triad density" is represented by the functional derivative underline underline{*}{ vartheta}B:= δ / δ { buildrel pm over { underline{A}B}} with respect to the canonically conjugate Ashtekar variable buildrel pm over{ underline{A}B}. This provides a mapping from the Hamiltonian constraint of gravity with a cosmological term to the Chern Simons three form [7] of the Ashtekar Sen connection, see

In a fiber bundle approach, one introduces first the bundle of affine frames A(M):= P( Mn, A, n,R), π, δ where π denotes the projection to the base manifold and δ the (left) action of the structure group A(n,R) on the bundle. Active affine gauge transformations are the vertical automorphisms of A(M). Similarly as the diffeomorphisms of the base manifold Mn, they form the infinite dimensional group { cal A}(n, R):=C∞( AM) timesAd A(n, R). The group { cal G}{ cal L}(n, R):=C∞(AM) timesAdGL (n, R) of linear gauge transformations and the group { cal T}(n, R):=C∞ (AM) timesAd Rn of local translations are subgroups of { cal A}(n, R). Taking the cross section in the associated bundle is abbreviated by C∞ and Ad denotes the adjoint representation with respect to GL(n,R). Because of its construction, the group of local translations { cal T}(n, R) is locally isomorphic to the group of active diffeomorphisms Diff(n,R) of the manifold, cf.
