Unstability order for an unstable surface of a rank 2 reflexive sheaf. (English) Zbl 0659.14014
In this paper one obtains sharp bounds for the order of unstability of an unstable surface of a rank 2 stable (unstable) reflexive sheaf on \(P^ 3\) in terms of the degree of the surface and the Chern classes (and also the order of unstability) of the sheaf.
