Unfortunately, characterising the velocity field in cosmological N-body simulations is inherently complicated by two facts: i) The velocity field becomes manifestly multi-valued after shell-crossing and has discontinuities at caustics. This is due to the collisionless nature of dark matter. ii) N-body simulatio","authors_text":"(2) CEFCA, (3) KIPAC), Oliver Hahn (1), Raul E.
