Fitting ideals and multiple points of surface parameterizations
Given a birational parameterization ϕ of an algebraic surface S⊂P3, the purpose of this paper is to investigate the sets of points on S whose pre-image consists of k or more points, counting multiplicities. These points are described explicitly in terms of Fitting ideals of some graded parts of the...
