Parametrized theories, making EM even ¿gaugier?
|Authors:||Margalef-Bentabol, Juan CSIC ORCID CVN||Issue Date:||11-Jul-2016||Citation:||21st International Conference on General Relativity and Gravitation (GR21) (2016)||Abstract:||Parametrized field theories provide interesting examples of relatively simple diff- invariant systems, which can be then used as good toy models to understand some subtle features of General Relativity. In this talk, relying on the space of embeddings, I will explain some interesting aspects of the parametrized electromagnetic field, as it is one of the simplest models with gauge symmetries. In particular I will focus on how its primary constraint submanifold can be divided into sectors where different Hamiltonian dynamics take place, and show how the Gauss law comes into play (spoiler alert, it is not a constraint)||Description:||Presentación 43 diapositivas; 21st International Conference on General Relativity and Gravitation; New York (USA); 11-15 July 2016; http://www.gr21.org/program.html||URI:||http://hdl.handle.net/10261/155587|
