Algorithm for computing the moduli space of pointed Gorenstein curves with Weierstrass gap sequence 1,2, ... ,g-2,lambda,2g-3

摘要

An algorithm for computing the moduli space of pointed Gorenstein curves with Weierstrass gap sequence 1, 2, . . . , g - 2, lambda, 2g - 3, where 3g - 5 < 2lambda < 4g - 8 and g greater than or equal to 6, is given. This algorithm consists in deforming a nonreduced reducible canonical curve by the method of Stohr. (C) 2004 Elsevier Inc. All rights reserved.
