Generalizations of the Pontryagin and Husain-Kuchař actions to manifolds with boundary
J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol +1
In this paper we study a family of generalizations of the Pontryagin and Husain-Kuchař actions on manifolds with boundary. In some cases, they describe well-known models---either a…

Dirac's algorithm in the presence of boundaries: a practical guide to a geometric approach
J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol +1
The goal of this paper is to propose and discuss a practical way to implement the Dirac algorithm for constrained field models defined on spatial regions with boundaries. Our metho…
