This may be due to that the B-field that appears in the doubled metricdoes not necessarily coincide with the B-field in physical space. Theeventual physical B-field after we project our theory down from thedoubled space is a combination of the doubled geometry properties (i.e.,the component B of the doubled metric) and the orientation of double D-branes.[0712.1026; 0806.1783; 0902.4032; 0904.0380] This may cause more complicated B-field dependence in the reducedaction from double formalism than the standard DBI.Here comes your footerPage 38
In the conventional worldsheet action, the boundary gauge transformationfor A is related to the bulk gauge transformation of B. But this is not clear inthe doubled formalism because O(n,n) mixes the gauge symmetry anddiffeomorphism.Here comes your footer Page 39
