Unramified covers and branes on the Hitchin system
Emilio Franco, Peter Gothen, André Oliveira +1
We study the locus of the moduli space of Higgs bundles on a curve given by those Higgs bundles obtained by pushforward under an unramified cover. We equip these loci with a hyperh…
Branes on the singular locus of the Hitchin system via Borel and other parabolic subgroups
Emilio Franco, Ana Peón-Nieto
We study mirror symmetry on the singular locus of the Hitchin system at two levels. Firstly, by covering it by (supports of) -branes, corresponding to Higgs bundles reducing…
Mirror symmetry for Nahm branes
Emilio Franco, Marcos Jardim
The Dirac--Higgs bundle is a hyperholomorphic bundle over the moduli space of stable Higgs bundles of coprime rank and degree. We provide an algebraic generalization to the case of…
Continuous families of divisors, paracanonical systems and a new inequality for varieties of maximal Albanese dimension
Margarida Mendes Lopes, Rita Pardini, Gian Pietro Pirola
Given a smooth complex projective variety X, a line bundle L of X an element v of H^1(O_X) and a section s in H^0(L) that deforms to first order in the direction v, we give a suffi…
Polygons in Minkowski three space and parabolic Higgs bundles of rank two on CP^1
Indranil Biswas, Carlos Florentino, Leonor Godinho +1
Consider the moduli space of parabolic Higgs bundles (E,Φ) of rank two on CP^1 such that the underlying holomorphic vector bundle for the parabolic vector bundle E is trivial. It i…
