Abstract
In this paper we give an example of two composants X and X,o of the Hilbert scheme of space curves (i.e. components of subschemes with constant cohomology) satisfying the condition of semi-continuity (the cohomology of curves in X is less than the cohomology of curves in X,o) but not the property X 0⋂[Xbar]≠Ø.Keywords
