The inner structure of Zeldovich' pancakes
E. Aurell, D. Fanelli, S. N. Gurbatov +1
The evolution of a planar perturbation in a Einstein-de Sitter Universe is studied using a previously introduced Lagrangian scheme. An approximate discrete dynamical system is deri…

Asymptotic behavior of a stratified perturbation in a three dimensional expanding Universe
D. Fanelli, E. Aurell
The non-linear evolution of a stratified perturbation in a three dimensional expanding Universe is considered. A general Lagrangian scheme (Q model) is introduced and numerical inv…

On the decay of Burgers turbulence
S. N. Gurbatov, S. I. Simdyankin, E. Aurell +2
This work is devoted to the decay ofrandom solutions of the unforced Burgers equation in one dimension in the limit of vanishing viscosity. The initial velocity is homogeneous and…
