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.
