By studying sections, they are able to determine all Chern classes c1,c2,c3 for which such sheaves exist. As an application they describe a stratification of the moduli space MP2(−1,c2) of stable rank 2 sheaves on P2 with given Chern classes c1=−1 and c2. This space can be viewed as a compactification of the moduli space of stable rank 2 vector bundles over the projective plane.fraFaisceaux semi-stables de rang 2 sur P3journal articlehttp://gallica.bnf.fr/ark:/12148/cb34394200t/date.r=COMPTES+RENDUS+DE+L+ACADEMIE+DES+SCIENCES+SERIE+I-MATHEMATIQUE.langEShttp://gallica.bnf.fr/?lang=ESrestricted access512Álgebra1201 Álgebra
