Atiyah class
WebMay 2, 2012 · Metrics We provide generalizations of the notions of Atiyah class and Kodaira-Spencer map to the case of framed sheaves. Moreover, we construct closed two-forms on the moduli spaces of framed sheaves on surfaces. As an application, we define a symplectic structure on the moduli spaces of framed sheaves on some birationally ruled … WebAtiyah–Jones conjecture it would now suffice to show that the maps tk in-duce isomorphism in homology and homotopy through a range. In 1993, Boyer, Hurtubise, Milgram and Mann [BHMM] proved that the Atiyah–Jones conjecture holds for the sphere S4 and in 1995, Hurtubise and Mann [HM] proved that the conjecture is true for ruled surfaces.
