Title:
On the Stochastic Quantisation of Quantum Gravity with a second order Langevin equation and its physical predictions for the early cosmology
Speaker:
Abstract:
Euclidean quantum gravity might be defined by a stochastic quantisation governed by a second order Langevin equation - NOT by a first order stochastic equation as in standard Parisi Wu formulation -, so that interesting acceleration effects occur in the Langevin process. The prediction of the stochastic 5d theory of 4d gravity with a (+----) signature is that there will a transition from an oscillating 5d phase that defines quantum gravity toward the classical 4d theory where the Minkowski time has emerged.
