Hamiltonian spinfoam gravity

Understand

This paper presents a Hamiltonian formulation of spinfoam-gravity, which leads to a straight-forward canonical quantisation.

• To begin with, we derive a continuum action adapted to the simplicial decomposition.
• The equations of motion admit a Hamiltonian formulation, allowing us to perform the constraint analysis.
• We do not find any secondary constraints, but only get restrictions on the Lagrange multipliers enforcing the reality conditions.
