Compactifications of moduli of $G$-bundles and conformal blocks

  title={Compactifications of moduli of \$G\$-bundles and conformal blocks},
  author={Avery S. Wilson},
For a stable curve of genus g ≥ 2 and simple, simply connected group G, we show that sections of determinant of cohomology on the stack of G-bundles extend to the normalization of its closure in the stack of Schmitt’s honest singular G-bundles. We use this to show that the conformal blocks algebra A onMg is finitely generated and that closed fibers of ProjA → Mg can be interpreted as normalized moduli spaces of singular G-bundles. 


Conformal blocks and generalized theta functions
LetSUXr be the moduli space of rankr vector bundles with trivial determinant on a Riemann surfaceX. This space carries a natural line bundle, the determinant line bundleL. We describe a canonical
Degenerations of the moduli spaces of vector bundles on curves I
LetY be a smooth projective curve degenerating to a reducible curveX with two components meeting transversally at one point. We show that the moduli space of vector bundles of rank two and odd
Degenerations of the moduli spaces of vector bundles on curves II (generalized Gieseker moduli spaces)
LetX0 be a projective curve whose singularity is one ordinary double point. We construct a birational modelG(n, d) of the moduli spaceU(n, d) of stable torsion free sheaves in the case (n, d)= 1,
Chern classes of conformal blocks
We derive a formula for the Chern classes of the bundles of conformal blocks on \bar{M}_{0,n} associated to simple finite dimensional Lie algebras and explore its consequences in more detail for sl_2
Singular principal G-bundles on nodal curves
In the present paper, we give for the first time a general construction of compactified moduli spaces for semistable $G$-bundles on an irreducible complex projective curve $X$ with exactly one node,
Degeneration of SL(n)-bundles on a reducible curve
We constructed a projective moduli space of semistable torsion free sheaves with `fixed determinant' on a reducible curve. When a family of smooth curves degenerates to the reducible curve, our

The Langlands lemma and the Betti numbers of stacks of $G$--bundles on a curve
In this note we show that the Langlands lemma from the theory of Eisenstein series can be used to invert the recursion relation for the Poincar\'e series of the open substack of semi-stable

In this paper, we answer two long-standing questions on the classification of G -torsors on curves for an almost simple, simply connected algebraic group G over the field of complex numbers. The
Singular principal bundles on reducible nodal curves
Studying degenerations of moduli spaces of semistable principal bundles on smooth curves leads to the problem of constructing and studying moduli spaces on singular curves. In this note, we will see
