Quantization of Maxwell's equations on curved backgrounds and general local covariance

By Claudio Dappiaggi and Benjamin Lang


We develop a quantization scheme for Maxwell's equations without source on an arbitrary four dimensional globally hyperbolic spacetime. The field strength tensor is the key dynamical object and it is not assumed a priori that it descends from a vector potential. It is shown that, in general, the associated field algebra can contain a non trivial centre and, on account of this, such a theory cannot be described within the framework of general local covariance unless further restrictive assumptions on the topology of the spacetime are made.Comment: 23 pages, 1 figure, explicit construction of the universal algebra added in section
