Non-Perturbative One-Loop Effective Action for Electrodynamics in Curved Spacetime
Guglielmo Fucci
In this paper we explicitly evaluate the one-loop effective action in four dimensions for scalar and spinor fields under the influence of a strong, covariantly constant, magnetic f…

Non-Perturbative Aspects of Quantum Electrodynamics on Curved Space and Investigations in Matrix Gravity
Guglielmo Fucci
In the first part of this Dissertation, we study non-perturbative aspects of quantum electrodynamics on Riemannian manifolds by using heat kernel asymptotic expansion techniques. H…
