✦ Synopsis


Denote by M I(k) the moduli space of k-instanton bundles E of rank 2 on P 3 = P(V ) and by Z k (E) the scheme of k-jumping lines. We prove that

We prove also that E is special if and only if Z k (E) is a smooth conic. The action of SL(V ) on the moduli of special instanton bundles is studied in detail.
