Consider a rational projective curve C of degree d over an algebraically closed field k. There are n homogeneous forms g1;:::;g n of degree d in B = kk(x;y) which parameterize C in a birational, base point free, manner. We study the singularities of C by studying a Hilbert-Burch matrix ' for the row vector (g1;:::;g n). In the "General Lemma" we use the generalized row ideals of ' to identify the singular points on C, their multiplicities, the number of branches at each singular point, and the… CONTINUE READING
