The Lazarsfeld-Rao property on an artihmetically Gorenstein variety
(1993)We show how to use all the machinery of liaison techniques for the study of two-codimensional subschemes of a smooth arithmetically Gorenstein subscheme of Pn. -
The Lazarsfeld-Rao problem for liaison classes of two-codimensional subschemes of Pn
(1991)We show how to use all the machinery of liaison techniques for the study of two-codimensional subschemes of a smooth arithmetically Gorenstein subscheme of Pn. -
Arithmetically normal sheaves
(1987)We rind the upper bound for the third Chem class of a curvilinear sheaf with seminatural cohomology, and we determine all the triples of Chem classes for which there exist two different kinds of seminatural cohomology. ... -
Deformations of Arithmetically Cohen-Macaulay subvarieties of Pn
(1989)We show that every arithmetically Cohen-Macaulay two-codimensional subscheme ofPn can be deformed to a reduced union of two-codimensional linear subvarieties. This problem (classical for curves with the name of Zeuthen ... -
On curves with natural cohomology and their deficiency modules
(1993)The minimal free resolution of the Hartshorne-Rao module of a curve with natural cohomology is studied, and conditions are given on the degrees and the ranks of the terms of this resolution. -
Construction of families of curves from finite length graded modules
(1990)We construct particular families of projective space curves starting from finite length graded modules, exhibiting several phenomena of specializations. The main tool is the Rao construction via a free resolution of the module. -
Deficiency modules and specializations
(1990)Given a family of curves in the projective space we study how their deficiency modules can change. This has a geometrical translation in the problem of determining how the liaison class of a flat family of curves can change. ... -
A note on the postulation of maximal rank curves
(1987)Let s be the lowest degree of a surface containing a maximal rank curve Y. We want to compare the dimension of the space of the surfaces of degree s containing Y with the dimension of the space of the surfaces of degree ... -
Numerical invariants of rank-2 arithmetically buchsbaum sheaves
(1989)We study rank-2 reflexive sheaves on P3 whose sections are Buchsbaum curves, giving vanishing theorems for the cohomology and bounds and gaps for the existence range of their Chern classes. These results are applied to ... -
Getting out of the seclusion trap? Work as meaningful occupation for subjective well-being of asylum seekers in South Tyrol, Italy
(2017)This study explicitly links social aspects of the subjective well-being of asylum seekers and the lack of valued and meaningful occupation during the asylum application process. In bringing subjective personal experiences ... -
Irreducible families of curves with fixed cohomology
(1989)One of the classical ways for studying the problem of the classification of curves in the projective space was the investigation of the irreducible families of curves, and this approach led to the notion of Hilbert scheme. ... -
The variety of module structures
(1990)Introduction. In this paper we study how is "structured" the set of curves of the projective space having assigned dimensions for the cohomology groups Hi (P3, Jx (t)). In particular, we show that almost always this locally ... -
I fondamenti relazionali e sociologici del teatro
(2017)The theatrical performance is a powerful and radical expression of the relation between society and creative action. This paper will inquire some of the most relevant theoretical issues in sociology of the theatre in order ... -
A Comparative Study of Active Play on Differently Designed Playgrounds
(2013)The physical and social environment of children in cities is continuously changing. Knowledge about the positive effects of natural play experiences within the child’s development is becoming widely known. Affordances of ... -
