Geometry, constraints and boundaries. It takes three to tango.

Constrains appear quite naturally in many interesting physical systems such as EM, gravity or parametrized systems. If we are interested in quantizing such systems, it seems necessary to have a precise Hamiltonian formulation. The Dirac's algorithm addresses this problem quite nicely when no boundaries are present, but… boundaries are also very natural! Through some examples I will show the limits of the Dirac's algorithm in the presence of boundaries and introduce an alternative algorithm, called GNH, that can tackle these systems.
