Arithmetically normal sheaves
Bolondi G
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. This is done by introducing the notion of arithmetically normal sheaf.

Deformations of Arithmetically Cohen-Macaulay subvarieties of Pn
Bolondi G; MirĂ² Roig RM
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 problem) was solved for curves by F.Gaeta.

On the motion of test particles in a fluctuating gravitational field
Modanese G
In this paper the "free fall" motion of a test tetrad in a weak gravitational field is studied. This is done with the intention of exploring the geometry locally through geodesics and parallel transport. By use of the so-called "radial gauge" the action of the field on the test tetrad just in terms of the Riemann tensor is expressed. The average effect of small quantized fluctuations of the field can thus be computed using the Feynman-De Witt propagator. Since the dimension L of the test particle must be finite, only fluctuations of wavelength lambda > L have to be considered. The corresponding corrections to the geometry are proportional to l(Planck)/L. Such dependence on L spoils, in fact, a genuine geometrical description.
