ADM formulation and Hamiltonian analysis of Coincident General Relativity

Understand

We consider a simpler geometrical formulation of General Relativity based on non-metricity, known as Coincident General Relativity.

• We study the ADM formulation of the theory and perform a detailed Hamiltonian analysis.
• We explicitly show the propagation of two physical degrees of freedom, as it should, even though the role of boundary terms and gauge conditions is significantly altered.
• This might represent an alternative promising new route for numerical relativity and canonical quantum gravity.
