Numerical simulations, general dynamical considerations and some observations constrain in different way the inner asymptotic slope of the dark matter (DM) halo density profile. The dynamical theory of the Fundamental Plane (FP) based on the existence of a maximum in the Clausius' Virial potential energy (CV) of a galaxy stellar component which is completely embedded inside a DM halo, adds a contribution to the controversy in favour of a cored profile.

Abstract
Numerical simulations, general dynamical considerations and some observations constrain in different way the inner asymptotic slope of the dark matter (DM) halo density profile. The dynamical theory of the Fundamental Plane (FP) based on the existence of a maximum in the Clausius' Virial potential energy (CV) of a galaxy stellar component which is completely embedded inside a DM halo, adds a contribution to the controversy in favour of a cored profile.
