Families of Hitchin Systems in Type-D
Aswin Balasubramanian, Jacques Distler, Ron Donagi +1
The Coulomb branch geometry of a 4d SCFT is encoded in the data of a complex integrable system. In class-S, this is the Hitchin System (of ADE type) on the puncture…
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.
