Moduli spaces of SL(r)-bundles on singular irreducible curves

Xiaotao Sun

For a stable irreducible curve and a torsion free sheaf on of rank one and degree , D.S. Nagaraj and C.S. Seshadri ([NS]) defined a closed subset $\Cal U_X(r,L)$ in…

Degeneration of SL(n)-bundles on a reducible curve

Xiaotao Sun

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 reducib…
