contact the instructor.
This will be an introductory graduate course in generalized geometry, with a special emphasis on generalized K\"ahler geometry. The main references for this class are the published papers on generalized complex and K\"ahler geometry, but we will also draw from more recent developments in the physics literature.
A basic familiarity with manifolds will be assumed; here is a list of topics which will be covered in the lecture course:
Gerbes, B-fields, and exact Courant algebroids;
Relation to sigma models in physics;
Linear algebra of a split-signature real bilinear form; pure spinors;
Generalized Riemannian structures and the generalized Hodge star;
Integrability, Dirac structures, Lie algebroids and bialgebroids;
Generalized complex structures; examples of such;
Generalized holomorphic bundles
Generalized K\"ahler geometry;
Hodge decomposition theorem for Generalized K\"ahler structures;
Equivalence theorem Generalized K\"ahler=Bihermitian
The generalized K\"ahler potential
Generalized K\"ahler reduction
The generalized K\"ahler–Ricci flow of Streets and Tian
