In the dot-product of the inverse factors of the Vandermonde-matrix occur series of the type 1 + 1 / 2 + 1 / 3 + ⋯ which -if cohenrently interpreted with the whole inversion assumption- would mean the infinite expression for log ( 0) (and similar for its powers) which is/are not regularizable and remain singularities. So there is no inverse.
