Phys. Rev. D 12, 385–396 (1975)Time-evolution problem in regge calculusSee Also: Erratum Received 30 September 1974; published in the issue dated 15 July 1975 The simplectic approximation to Einstein's equations ("Regge calculus") is derived by considering the net to be actually a (singular) Riemannian manifold. Specific nets for open and closed spaces are introduced in terms of which one can formulate the general time-evolution problem, which thereby reduces to the repeated solution of finite sets of coupled nonlinear (algebraic) equations. The initial-value problem is also formulated in simplectic terms. © 1975 The American Physical Society URL:
