The purpose of this Note is to show that loci of (special) Weierstrass points on the fibers of a family X over S of smooth curves of genus greater than 2 can be studied by simply pulling back the Schubert calculus naturally living on a suitable Grassmann bundle over X. Using such an idea we prove new results regarding the decomposition in in the Chow group of X of the class of the locus of Weierstrass points locus of Weierstrass points having weight at least 3 as the sum of classes of Weierstrass points having “bounded from below” gaps sequences.

Abstract
The purpose of this Note is to show that loci of (special) Weierstrass points on the fibers of a family X over S of smooth curves of genus greater than 2 can be studied by simply pulling back the Schubert calculus naturally living on a suitable Grassmann bundle over X. Using such an idea we prove new results regarding the decomposition in in the Chow group of X of the class of the locus of Weierstrass points locus of Weierstrass points having weight at least 3 as the sum of classes of Weierstrass points having “bounded from below” gaps sequences.Pubblicazioni consigliate
