МногообразиеMQ(-1; 2) модулей расслоений ранга 2 с классами Черна c1 = -1, c2 = 2 на Q было изучено Оттавиани и Шуреком в 1994 г. В 2007 г. автором было получено описание замыкания многообразия MQ (-1; 2) в схеме MQ(2;-1; 2; 0). В настоящей статье доказывается, что в MQ(2;-1; 2; 0) существует единственная неприводимая компонента, отличная от MQ(-1; 2), являющаяся рациональным многообразием размерности 10.</p></abstract><trans-abstract xml:lang="en"><p>In this paper we consider the scheme MQ( 2;¡1; 2; 0 ) of stable torsion free sheaves of rank 2 with Chern classes c1 = -1, c2 = 2, c3 = 0 on a smooth 3-dimensional projective quadric Q. The manifold MQ(-1; 2) of moduli bundles of rank 2 with Chern classes c1 = -1, c2 = 2 on Q was studied by Ottaviani and Szurek in 1994. In 2007 the author described the closure MQ (-1; 2) in the scheme MQ(2;¡1; 2; 0). In this paper we prove that in MQ(2;¡1; 2; 0) there exists a unique irreducible component diferent from MQ (¡1; 2) which is a rational variety of dimension 10.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компактификация</kwd><kwd>схема модулей</kwd><kwd>когерентный пучок ранга</kwd></kwd-group><kwd-group xml:lang="en"><kwd>compactification</kwd><kwd>moduli scheme</kwd><kwd>coherent torsion free sheave of rank 2</kwd><kwd>3-dimensional quadric</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Szurek M. , Wisniewski J.
