Three Roads to the Geometric Constraint Formulation of Gravitational Theories with Boundaries
The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most popular of them being the one developed by Dirac. Here, we discuss other approaches to this problem that rely on the dir...
