Abstract [en]

We review the physical derivation of generalized Kähler geometry of [A. Bredthauer, et. al., Lett. Math. Phys. 77 (2006) 291 [ hep-th/0603130 ]]. The relation between supersymmetry and complex geometry has long been known. In particular, for a two-dimensional sigma model with N = ( 2 , 2 ) worldsheet supersymmetry, the target space is bi-hermitian. Recent developments in mathematics shed new light on this topic. Here, we rederive and explain the results of Gualtieri regarding the equivalence between generalized Kähler and bi-hermitian geometry from the sigma model point of view and show how this relation is obtained by considering the Lagrangian and the Hamiltonian formulation of the sigma model.
