N=2 world-sheet approach to D-branes on generalized Kaehler geometries: II. Dualities

TL;DR

This paper explores how T-duality transformations in N=2 boundary superspace can systematically generate coisotropic D-branes on generalized Kaehler geometries, expanding the understanding of D-brane configurations beyond hyper-Kaehler spaces.

Contribution

It introduces a systematic method for constructing coisotropic D-branes on generalized Kaehler geometries using T-duality in N=2 boundary superspace, with explicit examples.

Findings

T-duality transformations relate different D-brane configurations.

Coisotropic branes can be constructed on non-hyper-Kaehler spaces.

The approach broadens the class of geometries supporting D-branes.

Abstract

Following the general formalism reviewed in 0810.5355 [hep-th] we present several examples of possible D3-brane configurations on four-dimensional generalized Kaehler geometries. We will discuss T-duality transformations in N = 2 boundary superspace and apply the duality transformations to the constructed D3-branes. The duality transformations lead to a systematic method to construct coisotropic branes, even on target spaces that are not hyper-Kaehler.
