Curves of maximal genus in P^5
Rita Ferraro
Let C be a reduced, irreducible, not degenerate curve, not contained on surfaces of degree <s; when d=deg(C) is large with respect to s, the arithmetic genus p_a(c) is bounded by a…

Linkage on singular rational normal surfaces and three-folds with application to the classification of curves of maximal genus
Rita Ferraro
In this paper the author provides a generalization of classical linkage, i.e. linkage by a complete intersection, in a different context. Namely she looks at residuals in the schem…

Weil divisors on rational normal scrolls
Rita Ferraro
The aim of this paper is to study Weil divisors on a singular rational normal scroll X. In particular the author describes explicitly the group of divisorial sheaves associated to…
