Hello could someone give some info about the "Numerical solution" to GR...is this a field of "Computational Physics"?..
- What i know is that you take the Hyper-surface, and you " split " it into triangles..and use the ¿angles? of every triangle as finite-coordinates..then you get a problem with finite degrees of freedom...but What happens with the metric, Riemann Tensor Energy-momentum tensor in this discrete space-time?..could you use discrete espace but continuous time so the usual Einstein Lagrangian becomes a finite one in the form:
L(q_i ,\dot q_i ,t) so it's easier to "Quantize" than the continuous one?..
- Main questions: how do you define g_{ab} R_{ab} and other quantities into a finite "triangularized" surface..thanks
