Exceptional sequences of line bundles on projective bundles

Klaus Altmann, Andreas Hochenegger, Frederik Witt

For a vector bundle we investigate exceptional sequences of line bundles on the total space of the projectivisation . In…

The structure of exceptional sequences on toric varieties of Picard rank two

Klaus Altmann, Frederik Witt

For a smooth projective toric variety of Picard rank two we classify all exceptional sequences of invertible sheaves which have maximal length. In particular, we prove that unlike…

Toric co-Higgs sheaves

Klaus Altmann, Frederik Witt

We characterise and investigate co-Higgs sheaves and associated algebraic and combinatorial invariants on toric varieties. In particular, we compute explicit examples.

Asymptotic Geometry of the Hitchin Metric

Rafe Mazzeo, Jan Swoboda, Hartmut Weiss +1

We study the asymptotics of the natural metric on the Hitchin moduli space with group . Our main result, which addresses a detailed conjectural picture ma…

Holonomy rigidity for Ricci-flat metrics

Bernd Ammann, Klaus Kroencke, Hartmut Weiss +1

On a closed connected oriented manifold we study the space of all Riemannian metrics which admit a non-zero parallel spinor on the universal covering. Such…

Limiting configurations for solutions of Hitchin's equation

Rafe Mazzeo, Jan Swoboda, Hartmut Weiss +1

We review recent work on the compactification of the moduli space of Hitchin's self-duality equation. We study the degeneration behavior near the ends of this moduli space in a set…
