Abstract
Efficient expansions of the gravitational field of (dark) haloes have two
main uses in the modelling of galaxies: first, they provide a compact
representation of numerically-constructed (or real) cosmological haloes,
incorporating the effects of triaxiality, lopsidedness or other distortion.
Secondly, they provide the basis functions for self-consistent field expansion
algorithms used in the evolution of
