Linear generalised complex structures

Arbeitsgruppenseminar Analysis

Malte Heuer (University of Hamburg)

Generalised complex structures were introduced by Nigel Hitchin and studied by Marco Gualtieri as a unification of complex and symplectic structures. In this talk I will first recall basic definitions in generalised geometry and then introduce linear generalised complex structures on vector bundles. We will see that these are a natural generalisation of holomorphic vector bundles and how they can be studied via adapted linear splittings and Dorfman connections. We show an equivalence between linear generalised complex structures on a vector bundle $E$ and certain complex Lie algebroid structures on $TM\oplus E^*$. The talk is based on joint work with Madeleine Jotz Lean.
