Positivity for Higgs vector bundles: criteria and applications

Ugo Bruzzo, Armando Capasso, Beatriz Graña Otero

Working in the category of smooth projective varieties over an algebraically closed field of characteristic 0, we review notions of ampleness and numerical nefness for Higgs bundle…

Seiberg-Witten differentials on the Hitchin base

Ugo Bruzzo, Peter Dalakov

In this note we describe explicitly, in terms of Lie theory and cameral data, the covariant (Gauss--Manin) derivative of the Seiberg--Witten differential defined on the weight-one…

Codimension bounds for the Noether-Lefschetz components for toric varieties

Ugo Bruzzo, William D. Montoya

For a quasi-smooth hyper-surface $X$ in a projective simplicial toric variety $P$ , the morphism $i : H^{p} (P) \to H^{p} (X)$ induced by the inclusion is injective for $p = d$ and an isomorp…

Flags of sheaves, quivers and symmetric polynomials

Giulio Bonelli, Nadir Fasola, Alessandro Tanzini

We study the representation theory of the nested instantons quiver presented in [1], which describes a particular class of surface defects in four-dimensional supersymmetric gauge…
