Oct 23, 2010 at 22:37 comment added David MJC Well, not really: $T\oplus T^*$ already has a Dirac structure, namely the maximal isotropic subspace $T$. Generalized geometry does not necessarily concern the study of other Dirac structures. This links with Urs' answer, and I will add a bit to my answer below.

Inlcuded Dirac structures
Oct 23, 2010 at 2:24 comment added David Carchedi Ah- right, so you mean Dirac structures, of course! I'll update it.
Oct 22, 2010 at 23:45 comment added David MJC Unfortunately, I cannot edit your post to clarify that you are referring to geometric structures on $T\oplus T^*$, not just orthogonal complex structures. But I am willing to elaborate on my answer in due course anyway (despite being very busy IRL). I hope other MO contributors will provide answers too.
Oct 22, 2010 at 23:19 comment added Yaniel Cabrera @both: if generalized complex structures are different from generalized geometries, then my question refers to generalized geometries. The type described in the comment right above this one. And yes David MJC, feel free to elaborate!
Oct 22, 2010 at 23:11 comment added David MJC No, it is more prosaic than that. Generalized geometry is about doing geometry on the generalized tangent bundle $T\oplus T^*$. It is not specifically about complex structures, but concerns more general reductions of the structure group of $T\oplus T^*$. In type IIA and IIB string theory, generalized complex structures play an important role, but the role of generalized geometry in string theory is broader than this.
Oct 22, 2010 at 22:55 comment added David Carchedi @Yaniel: feel free to update my edit if this is not exactly what you meant. @David: What other types of "generalized geometries" do you mean? Are you counting such things as orbifolds under this umbrella?
Oct 22, 2010 at 22:50 comment added David MJC The updated version changes the scope of the question. Generalized geometries play a much broader role in string theory that generalized complex structures do. If the question concerns the specific role played by generalized complex structures, then my answer to date (already brief 23/10) is inadequate.
Oct 22, 2010 at 22:46 comment added Yaniel Cabrera yes, the updated version is clearer. thanks.
Oct 22, 2010 at 22:41 comment added David Carchedi I hope you don't mind, but, in light of David MJC's answer, I figured out what you meant and have updated your question to be more clear.

Oct 22, 2010 at 21:54 comment added David Carchedi As worded, this question is too vague. Please define what you mean by "generalized geometries" as there are various interpretations of this phrase.
