The Euclidean contour rotation in quantum gravity

Abstract:

The talk will discuss the rotation of the contour of functional integration in quantum gravity from Lorentzian geometries to Euclidean geometries. In the usual framework of metric tensors, the functional integral does not have a good definition and so the formulas are necessarily heuristic. However, it is hoped that these formulas will provide exact mathematical results when applied to theories that are constructed with a fundamental Planck scale cut-off.

Noncommutative Geometry and Physics

Series comments: Noncommutative geometry is a very general mathematical paradigm arising from quantum mechanics. As such, it permeates different branches of mathematics and physics.

The series of monthly talks accompanies the special issue of Journal of Physics A and is intended to present the many facets of the emergence of noncommutativity in physics.
