Irreducibility of moduli of semi-stable chains and applications to U(P, q)-Higgs bundles
... Abstract. We give necessary and sufficient conditions for moduli spaces of semistable chains on a curve to be irreducible and non-empty. This gives in- formation on the irreducible components of the nilpotent cone of GL ...

Birationality of moduli spaces of twisted U(p, q)-Higgs bundles
... vector bundles with extra structure on a Riemann surface X have been intensively studied over the last ...decades. Higgs bundles constitute an important exam- ple, not least due to the non-abelian ...
Topological Mirror Symmetry for Parabolic Higgs bundles
... parabolic Higgs bundles is in many ways analogous to that of usual Higgs ...bolic Higgs bundles have subsequently been studied by many authors; we merely point to Boden–Yokogawa [9] and ...

Maximal Higgs bundles for adjoint forms via Cayley correspondence
... Given a real reductive Lie group G, the count of the connected components of the moduli spaces M(G) of G-Higgs bundles over a compact Riemann surface X of genus g > 2, has been a subject of intense study ...

The stability of exceptional bundles on complete intersection 3-folds
... Abstract. A very long-standing problem in Algebraic Geometry is to deter- mine the stability of exceptional vector bundles on smooth projective varieties. In this paper we address this problem and we prove that ...

Splitting criteria for vector bundles on the symplectic isotropic Grassmannian
... Abstract. We extend a theorem of Ottaviani on cohomological splitting criterion for vector bundles over the Grassmannian to the case of the symplectic isotropic Grassmanian. We find nec- essary and sufficient ...
Simplified modeling of EM field coupling to complex cable bundles
