Towards the consistent perturbative expansion in discrete gravity
V. M. Khatsymovsky
We consider correctly defining the perturbative expansion in a discrete gravity (simplicial or Regge calculus) needed to study physical effects like graviton loop corrections to Ne…

Discrete gravitational diagram technique in the soft synchronous gauge
V. M. Khatsymovsky
This paper develops our work on the consequences of the Regge calculus, where some edge length scale arises as an optimal starting point of the perturbative expansion with taking i…

Soft synchronous gauge: principal value prescription
V. M. Khatsymovsky
The synchronous gauge in gravity () is ill-defined due to the singularity at in the graviton propagator. Previously we studied "softening" this ga…
