Query: Generalized Yang-Mills theory and the D-brane effective action   Non-abelian gauge theories in the context of generalized complex geometry are
discussed. The generalized connection naturally contains standard gauge and
scalar fields, unified in a purely geometric way. We define the corresponding
Yang-Mills theory on particular subbundles of a Courant algebroid, known as
Dirac structures, where the generalized curvature is a tensor. Different Dirac
structures correspond to different known theories, such as the bosonic sector
of maximally supersymmetric Yang-Mills in ten and four dimensions and reduced
matrix models. Furthermore, we revisit the non-abelian world volume effective
action of D-branes in this formalism, where the gauge field on the brane and
the transverse scalars are unified, while the action does not contain pullbacks
of fields and its consistency with T-duality is verified at face value.
