Non-Linear Vorticity-Density Coupling in Lagrangian Dynamics

Non-Linear Vorticity-Density Coupling in Lagrangian Dynamics

We present a general Lagrangian formalism that allows for the treatment of vorticity. We give solutions for the rotational perturbations up to third-order in a flat background universe. We show how the vorticity affects the evolution of the density fluctuation in high-density regions.
