We will discuss a setting for orthogonal symmetries in quiver bundles which is derived from Derksen-

A twisted U(p,q)-Higgs bundle consists of a pair of holomorphic vector bundles on a Riemann surface,

It is well known that in any compact Kaehler manifold the exterior multiplication by a suitable pow

We explain how to calculate, in some particular cases, the Seidel representation of $\pi_1({\rm Ham}

The (Schottky) uniformization of Riemann surfaces motivated the search of a parametrization of holom

Character varieties are spaces of representations of finitely presented groups into real reductive L

Character varieties parametrize representations of the fundamental group of a variety into complex

Let G be a complex reductive Lie group, and consider Higgs(G) the moduli space of G-Higgs bundles. T

In this talk, we discuss the problem of classifying the closed and transitive homeomorphism groups

Chad Schoen (2007) used deformations to construct a family of smooth complex algebraic surfaces S w
