Hypersurface-Invariant Approach to Cosmological Perturbations
D. S. Salopek, J. M. Stewart
Using Hamilton-Jacobi theory, we develop a formalism for solving semi-classical cosmological perturbations which does not require an explicit choice of time-hypersurface. The Hamil…

The Zel'dovich Approximation and the Relativistic Hamilton-Jacobi Equation
D. S. Salopek, J. M. Stewart, K. M. Croudace
Beginning with a relativistic action principle for the irrotational flow of collisionless matter, we compute higher order corrections to the Zel'dovich approximation by deriving a…
