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…
Open maps of involutive quantales
Pedro Resende
By a map of involutive quantales is meant a homomorphism . Calling a map weakly open if has a left adjoint which satisfies the Frobenius reci…
Variational problems with long-range interaction
Nicola Soave, Hugo Tavares, Susanna Terracini +1
We consider a class of variational problems for densities that repel each other at distance. Typical examples are given by the Dirichlet functional and the Rayleigh functional \[ D…
Quantales and Fell bundles
Pedro Resende
We study Fell bundles on groupoids from the viewpoint of quantale theory. Given any saturated upper semicontinuous Fell bundle on an étale groupoid with locall…
