Abstract Fix a field K, a subset P ⊆ { 1 , … , k } × { 1 , … , m } and an integer δ ≤ min { k , m } . Let C ( m , k , P , K ) be the vector space of all k × m matrices with entries a i , j = 0 if (… Expand

Moduli of Prym curves

- E. Ballico, C. Casagrande, C. Fontanari
- Mathematics
- 15 April 2003

Here we focus on the compactification of the moduli space of curves of genus g together with an unramified double cover, constructed by Arnaud Beauville in order to compactify the Prym mapping. We… Expand

Very ample line bundles on blown-up projective varieties

- E. Ballico, M. Coppens
- Mathematics
- 1997

Let X be the blowing - up of the smooth projective variety V .H ere we study when a line bundle M onX is very ample and, if very ample, the k-very ampleness of the induced embedding of X.

On the weak non-defectivity of veronese embeddings of projective spaces

- E. Ballico
- Mathematics
- 1 June 2005

Fix integers n, x, k such that n≥3, k>0, x≥4, (n, x)≠(3, 4) and k(n+1)<(nn+x). Here we prove that the order x Veronese embedding ofPn is not weakly (k−1)-defective, i.e. for a general S⊃Pn such that… Expand

Non-reflexive projective curves of low degree

- E. Ballico, A. Hefez
- Mathematics
- 1 December 1991

This paper deals with the classification of projective curves of low degree, defined over fileds of positive characteristic, which have exceptional tangential behaviour. It also describes plane… Expand

Tensor ranks on tangent developable of Segre varieties

- E. Ballico, A. Bernardi
- Mathematics
- 30 October 2012

We describe the stratification by tensor rank of the points belonging to the tangent developable of any Segre variety. We give algorithms to compute the rank and a decomposition of a tensor belonging… Expand

COHERENT SYSTEMS WITH MANY SECTIONS ON PROJECTIVE CURVES

- E. Ballico
- Mathematics
- 1 March 2006

Here we give sufficient conditions for the existence of an α-stable (for all α > 0) coherent system (i.e. a vector bundle together with a linear subspace of its global sections) of type (d,n,k), k >… Expand
