Stratifying Quotient Stacks and Moduli Stacks,.∕.], where . is a projective scheme and . is a linear algebraic group with internally graded unipotent radical acting linearly on ., in such a way that each stratum [.∕.] has a geometric quotient .∕.. This leads to stratifications of moduli stacks (for example, sheaves over a projective scheme) suc

The Moduli Spaces of Sheaves on Surfaces, Pathologies and Brill-Noether Problems,rill-Noether problem for rational surfaces. In order to highlight some of the difficulties for more general surfaces, we show that moduli spaces of rank 2 sheaves on very general hypersurfaces of degree . in . can have arbitrarily many irreducible components as . tends to infinity.

The Topology of , and Its Compactifications,ns. The main emphasis lies on the computation of the cohomology for small genus and on stabilization results. We review both geometric and representation theoretic approaches to the problem. The appendix provides a detailed discussion of computational methods based on trace formulae and automorphic
