Non-linear vorticity-density coupling in Lagrangian dynamics
Makoto Sasaki, Masumi Kasai
We present a general Lagrangian formalism that allows the treatment of vorticity. We give solutions for the rotational perturbations up to the third-order in a flat background univ…

Relativistic Zel'dovich approximation in spherically symmetric model
Masaaki Morita, Kouji Nakamura, Masumi Kasai
We compare relativistic approximation methods, which describe gravitational instability in the expanding universe, in a spherically symmetric model. Linear perturbation theory, sec…
