Self-gravitating systems in a three-dimensional expanding Universe
Erik Aurell, Duccio Fanelli
The non-linear evolution of one-dimensional perturbations in a three-dimensional expanding Universe is considered. A general Lagrangian scheme is derived, and compared to two previ…

Heap-based algorithm for one-dimensional particle systems
Alain Noullez, Duccio Fanelli, Erik Aurell
A fast algorithm to study one-dimensional self-gravitating systems, and, more generally, systems that are Lagrangian integrable between collisions, is presented. The algorithm is e…
