Double null hamiltonian dynamics and the gravitational degrees of freedom
In this paper we review the Hamiltonian description of General Relativity using a double null foliation.We start by looking at the 2+2 version of geometrodynamics and show the role of the conformal 2-structure of the 2-metric in encoding (through the shear) the 2 gravitational degrees of freedom. In...
