Moduli stacks of Higgs bundles on stable curves
Oren Ben-Bassat, Sourav Das, Tony Pantev
In this article, we construct a flat degeneration of the derived moduli stack of Higgs bundles on smooth curves using the stack of expanded degenerations of Jun Li. We show that th…

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…
