A potential for generalized Kähler geometry

Abstract

We show that, locally, in the neighbourhood of a regular point, all geometric objects of Generalized Kähler Geometry can be derived from a function K, the “generalized Kähler potential”. The metric g and two-form B are determined as nonlinear functions of second derivatives of K. These nonlinearities are shown to arise via a quotient construction from an auxiliary local product (ALP) space.
