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) such that each stratum has a coarse moduli space.

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.

Geometric Invariant Theory of Syzygies, with Applications to Moduli Spaces,ed to make some progress in this program, that of polarized K3 surfaces of odd genus, and of genus six canonical curves. Applications of our results include effectivity statements for divisor classes on the moduli space of odd genus K3 surfaces, and a new construction in the Hassett-Keel program for the moduli space of genus six curves.
