The intersection of three quadrics in P^7 revisited
R. Donagi, T. Pantev
We show that the natural nc-space attached to an intersection of three quadrics in P^7 is truly non-commutative. In particular, its associated numerical K-lattice is not isomorphic…
The meromorphic Hitchin fibration over stable pointed curves: moduli spaces
Ron Donagi, Andres Fernandez Herrero
We construct a universal partial compactification of the relative moduli space of semistable meromorphic Higgs bundles over the stack of stable pointed curves. It parametrizes mero…
A measure on the moduli space of super Riemann surfaces with Ramond punctures
Ron Donagi, Nadia Ott
We construct a measure on the moduli space of super Riemann surfaces with Ramond punctures using the super Mumford isomorphism and a super period map.
On Generalized Pfaffians
Jacques Distler, Nathan Donagi, Ron Donagi
The determinant of an anti-symmetric matrix is the square of its Pfaffian, which like the determinant is a polynomial in the entries of . Studies of certain super conformal…
Twistor Hecke eigensheaves in genus 2
Ron Donagi, Tony Pantev, Carlos Simpson
Following the strategy outlined in [DP09] arXiv:math/0604617 and [DP22] arXiv:math/0604617 for bundles of rank 2 on a smooth projective curve of genus , we construct flat connec…
