Canonical formulation of Poincare BFCG theory and its quantization
Aleksandar Mikovic, Miguel A. Oliveira
We find the canonical formulation of the Poincare BFCG theory in terms of the spatial 2-connection and its canonically conjugate momenta. We show that the Poincare BFCG action is d…
Solution to the Cosmological Constant Problem in a Regge Quantum Gravity Model
Aleksandar Mikovic, Marko Vojinovic
We show that it is possible to solve the cosmological constant (CC) problem in a discrete quantum gravity theory based on Regge calculus by using the effective action approach and…
Cosmological Constant in a Quantum Gravity Theory for a Piecewise-linear Spacetime
Aleksandar Mikovic, Marko Vojinovic
We study the quantum contributions to the classical cosmological constant in a quantum gravity theory for GR with matter on a piecewise linear spacetime corresponding to a triangul…
Effective Actions for Regge State-Sum Models of Quantum Gravity
Aleksandar Mikovic
We study the semiclassical expansion of the effective action for a Regge state-sum model and its dependence on the choice of the path-integral measure and the spectrum of the edge…
