Fecha de publicación: | 9-oct-2019 | Editor: | Institute of Physics Publishing | Citación: | Journal of High Energy Physics 2019: 121 (2019) | Resumen: | In this paper we study a family of generalizations of the Pontryagin and Husain-Kuchǎr actions on manifolds with boundary. In some cases, they describe well- known models — either at the boundary or in the bulk — such as 3-dimensional Euclidean general relativity with a cosmological constant or the Husain-Kuchǎr model. We will use Hamiltonian methods in order to disentangle the physical and dynamical content of the systems that we discuss here. This will be done by relying on a geometric implementation of the Dirac algorithm in the presence of boundaries recently proposed by the authors. | Descripción: | 16 pags. -- Open Access funded by Creative Commons Atribution Licence 4.0 | Versión del editor: | http://dx.doi.org/10.1007/JHEP10(2019)121 | URI: | http://hdl.handle.net/10261/208550 | DOI: | 10.1007/JHEP10(2019)121 | Identificadores: | doi: 10.1007/JHEP10(2019)121 issn: 1029-8479 |
