Discrete gravitational diagram technique and corrections to the Newtonian potential
V. M. Khatsymovsky
Starting from simplicial Regge gravity, we use a bell-shaped form of the measure obtained using functional integration over connection. A "hypercubic" structure is considered (some…
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…
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 gauge…
Soft synchronous gauge in the perturbative gravity
V. M. Khatsymovsky
An attempt to directly use the synchronous gauge () in perturbative gravity leads to a singularity at in the graviton propagator. This is similar to…
On the gravitational diagram technique in the discrete setup
V. M. Khatsymovsky
This article is in the spirit of our work on the consequences of the Regge calculus, where some edge length scale arises as an optimal initial point of the perturbative expansion a…
On the discrete version of the Reissner-Nordström solution
V. M. Khatsymovsky
This paper generalizes our previous paper on the discrete Schwarzschild type solution in the Regge calculus, the simplicial electrodynamics earlier considered in the literature is…
