Title
Computing the singularities of rational surfaces.
Abstract
Given a rational projective parametrization P(s, t, v) of a rational projective surface S we present an algorithm such that, with the exception of a finite set (maybe empty) B of projective base points of P, decomposes the projective parameter plane as P-2(K) backslash B = U-k=1(l) S-k such that, if (s(0) : t(0) : v(0)) is an element of S-k, then P(s(0), t(0), v(0)) is a point of S of multiplicity k.
