01-JAN-04 – 31-DEC-06

Abstract
Zetafunctions as invariants of singularities: false candidate poles, actual poles and smallest poles. Properties of linear systems on varieties and secant varieties: ramification points o flinear systems on smooth curves, Grassmannians of secant spaces, secant varieties of curves and linear systems on blowings-up of the projective plane.
