You folks doing some fancy math there? Mmh, I'm not really sure why the Monster group paper turns up as 'related'. That kind of work sits squarely in the abstract algebra/group theory world, while what we do is far more applied. Think of it as a wavelet-inspired way of decomposing long-range potentials into near and far-field components to achieve better efficiency, along with tricks inspired from trapezoid rule integration to reduce the cost in higher dimensions. The first paper in the 'related' list, "Multiresolution separated representations of singular and weakly singular operators" is actually one that is really related, and has much of the theoretical background behind our work. It's actually nothing fancy at all from a theoretical standpoint, though rather complicated to implement (especially because speed comes from very aggressive truncations, so error analysis is difficult, critical and very easy to get wrong: you have to walk a fine line between speed and wrong results :).
