SUMMARY
The discussion centers on the implementation of torsion degrees of freedom in the causal dynamical triangulation (CDT) program, specifically in relation to Einstein-Cartan (EC) geometry. It is established that CDT has not incorporated matter degrees of freedom, resulting in calculations being performed in a torsion-free context. The participants confirm that torsion is non-propagating in EC theory, existing only where the matter spin current is present, which is currently absent in CDT.
