One of them expresses $\\Delta^C$ in terms of dimensions of some factors corresponding to a (multi-indexed) filtration on the ring ${\\cal O}_{C}$. The other one gives the coefficients of the Alexander polynomial $\\Delta^C$ as Euler characteristics of some explicitly described spaces (complements to arrangements of projective hyperplanes).
