Abstract:We give functorial moduli construction of pure parabolic sheaves, in the sense ofÁlvarez-Cónsul and A. King, using the moduli of filtered Kronecker modules which we introduced in our earlier work. We also use a version of S. G. Langton's result due to K. Yokogawa to deduce the projectivity of moduli of parabolic sheaves. As an application of functorial moduli construction, we can get the morphisms at the level of moduli stacks.

“…From this, it follows that λ U ∼ = D(F * ) and θ δ = θ F * . From the definition of U , we have λ U ∼ = λ N0 U and θ N0 δ = θ F * (see [2,Remark 6.3]). …”
In this article, we prove that the Faltings theta functions on moduli of parabolic bundles over a smooth projective curve can be used to give an explicit scheme-theoretic projective embedding.

“…In [5], a GIT-free construction of the moduli space of semistable parabolic bundles over a smooth projective curve is constructed using the analogous Faltings parabolic theta functions. In [3], it is proved that Faltings parabolic theta functions can be used to give a closed scheme-theoretic embedding of moduli of semistable parabolic bundles, using the results of [2].…”
In this article, we survey some results on geometric methods to study quiver representations, and applications of these results to sheaves, equivariant sheaves and parabolic bundles.
