We present the Lagrangian and Hamiltonian framework which incorporates null dust as a source into canonical gravity. Null dust is a generalized Lagrangian system which is described by six Clebsch potentials of its four–velocity Pfaff form. The Dirac–ADM decomposition splits these into three canonical coordinates (the comoving coordinates of the dust) and… CONTINUE READING
