Moduli Spaces of Framed Sheaves on Certain Ruled Surfaces over Elliptic Curves
Fix a ruled surface S obtained as the projective completion of a line bundle L on a complex elliptic curve C; we study the moduli problem of parametrizing certain pairs consisting of a sheaf E on S and a map of E to a fixed reference sheaf on S. We prove that the full moduli stack for this problem is representable by a scheme in some cases. Moreover, the moduli stack admits an action by the gro...
متن کاملModuli spaces of framed instanton sheaves on projective spaces
We introduce a generalization of the Atiyah-Drinfeld-Hitchin-Manin linear algebraic data and a generalization of Atiyah-Drinfeld-Hitchin-Manin equation, which are subsequently used to construct all framed instanton bundles on complex projective spaces. Using geometric invariant theory, we prove that the moduli spaces of framed instanton sheaves is a quasiprojective variety. We also provide a li...

متن کاملLectures on Moduli Spaces of Elliptic Curves
These informal notes are an expanded version of lectures on the moduli space of elliptic curves given at Zhejiang University in July, 2008. 1 Their goal is to introduce and motivate basic concepts and constructions important in the study of moduli spaces of curves and abelian varieties through the example of elliptic curves. The advantage of working with elliptic curves is that most constructio...
متن کاملArithmetic Aspects of Moduli Spaces of Sheaves on Curves
We describe recent work on the arithmetic properties of moduli spaces of stable vector bundles and stable parabolic bundles on a curve over a global field. In particular, we describe a connection between the period-index problem for Brauer classes over the function field of the curve and the Hasse principle for rational points on étale forms of such moduli spaces, refining classical results of ...
