Blow-ups in non-reductive GIT and moduli spaces of unstable vector bundles over curves
<p>We use non-reductive geometric invariant theory (NRGIT) to study a moduli problem involving pure sheaves of fixed Harder-Narasimhan type. The construction of moduli spaces for such sheaves can be reduced to the construction of NRGIT quotients of subschemes of Quot schemes. Hitherto NRGIT ha...
