A generalized complex structure $\mathcal{J}$ on a smooth manifold M is an assignment to each fiber of the extended tangent bundle $TM\oplus T^*M$ of an orthogonal linear complex structure in a locally compatible manner. The resulting formalism extends both complex and symplectic geometry, and was introduced in 2003 by Nigel Hitchin with an eye to string theory.

The aim of this learning seminar is first to review the foundational material, and then to acquaint ourselves with the state of the art and open questions.

Related constructions include,

  • Lie algebroids
  • Dirac structures
  • Courant algebroids
  • moment maps
  • generalized Kähler structures
  • T-duality

This seminar should appeal to students and researchers with interests in differential geometry and mathematical physics.
