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…
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…
