The heat kernel approach for calculating the effective action in quantum field theory and quantum gravity Article (PDF Available) October with 35 Reads How we measure 'reads'. Talk given by P. Haberl at the Conference Heat Kernel Techniques and Quantum Gravity, University of Manitoba, Winnipeg (Canada), Aug The calculation of one–loop effective actions as determinants of certain operators M has a long history, and numerous representations in closed form or as expansions are available [1].

I.G. Avramidi: "One-Loop Quantum Gravity and the Heat Kernel" Lecture 1. "Effective Action Approach in Gauge Field Theories and Quantum Gravity" Abstract: An overview of the effective action approach in quantum field theory and quantum gravity. Lecture 2. "Calculation of the Heat Kernel . The effective action of a quantum scalar field in a gravitational classical background is considered. In order to calculate it, it's transformed to Euclidean action and then renormalized (thrown away infinities) using zeta function and heat kernel technique then analytically continued back to Lorentzian s: 6.

Introduction to Quantum Effects in Gravity. (Note that the draft for this book is available for free on Winitzki’s web page.) And of course there are the classics by Bryce DeWitt which contain so much good physics – The Global Approach to Quantum Field Theory and Dynamical Theory of Groups and Fields. The quantisation of gauge theories usually procedes through the introduction of ghost fields and BRST symmetry. In the case of quantum gravity in the presence of boundaries, the BRST-invariant boundary value problem for the gauge field operators is non-elliptic, and consequently the definition of the effective action using heat-kernel techniques becomes problematic.
