标题： Extensions of Instantons

摘要： 本文利用Atiyah-Ward对应关系和Hitchin的一个定理，建立了射影空间上某些丛（它们是瞬子丛的扩张，特别是这些新的丛的第一陈类未必关于秩模0同余）与Gr(2,4)上的丛或S4球面上的丛之间的对应关系，这些丛配备了由与该丛相关的数据构造的某些联络。 这些扩张的丛的Monad被描述出来。 显示英文摘要

摘要： In this paper, using the Atiyah-Ward equivalence and a theorem of Hitchin, one makes to correspond to certain bundles on the projective space, which are extensions of instanton bundles (in particular, these new bundles may have the first Chern class not congruent to 0 modulo the rank), bundles on the grassmanian Gr(2,4) or on the sphere S4, equiped with certain connections constructed from data associated to the bundle. Monads for these extensions are described.
