Conformal courant algebroids and orientifold T-Duality
We introduce conformal Courant algebroids, a mild generalization of Courant algebroids in which only a conformal structure rather than a bilinear form is assumed. We introduce exact conformal Courant algebroids and show they are classified by pairs (L, H) with L a flat line bundle and H ∈ H 3(M, L) a degree 3 class with coefficients in L. As a special case gerbes for the crossed module (U(1) → Z2) can be used to twist TM ⊕ T*M into a conformal Courant algebroid. In the exact case there is a...[Show more]
