摘要: This is a theory of 2+1 gravity with spacelike lattice and continuous time. It derived from the Chern-Simons formulation gravity, in which frame vectors are canonically conjugate to SO(2, 1) connection. Dirac brackets computed for corresponding variables: link 3-vectors matrices define parallel transport across boundary between neighbouring faces. There set first-class constraints, state that analogues torsion curvature vanish locally. These generate local Lorentz rotations independent translations each site. One finds same complete observables as formulation.
