Corollary. There is a canonical bijection 0(MG;X ) ! 1 Proof. 1 (iv). 10. The line bundles on the moduli stack of G-bundles Let G be a connected simple complex group, X be a connected smooth projective complex curve. 1. 1. The line bundles on the in nite Grassmannian. 2. A natural line bundle. 3 c) of LGe and its restriction to L+ Ge. 5 we have a canonical character  G  L+ Ge p! 1 +G e ! 2 b)  : L[ G m; m hence a line bundle L 1 on the homogeneous space QGe . 1. A line in the in nite Grassmannian.

Such that  and  induce the same map in cohomology. Proof. Choose a representative Ke  of the cohomology of F and remark that  induces an isomorphism e in the derived category Dcb(S )  Rp F !  Rp (F _ ) !  K e  [ 1] Ke  !   which is still symmetric (this follows from the symmetry of  and standard properties of Grothendieck-Serre duality). 5 This is compatible with the usual signs: the dual of K  is supported in degrees 1 and 0; when translated to the right by 1, the di erential acquires a 1 sign.

The section E is non trivial; if there is t0 2 S such that H 0 (X; Et0 E ) 6= 0 then E 6= ;. 2. The pfaan line bundle. Suppose char(k) 6= 2 in this subsection. X . We will view  as  F _ such that  = _ , where F _ = Hom (F; q ! ). an isomorphism F ! 1. Lemma. If K  is a representative of the cohomology of F , then K  [ 1] is a representative of the cohomology of F _ . Here5 K  [ 1] denotes the complex supported in degrees 0 and 1  0 ! K 1 ! K 0 ! 0: Proof. In the derived category Dc (S ), we have  Rp (RHom (F; q !
