Optimized Lagrangian Approximations for Modelling Large--Scale Structure at Non--Linear Stages
T. Buchert, A. L. Melott, A. G. Weiss
Approximations to the exact solutions for gravitational instability in the expanding Universe are extremely useful for understanding the evolution of large--scale structure. We rep…

Optimized Lagrangian Approximations for Modelling Large--Scale Structure at Non--Linear Stages
T. Buchert, A. L. Melott, A. G. Weiss
We report on a series of tests of Newtonian Lagrangian perturbation schemes using N--body simulations for various power--spectra with scale--independent indices in the range t…
