In the end, the equation of motion for the double D-brane is to demandvanishing β-function:which can be derived from a DBI-like action:by assuming that F ab also satisfy the Bianchi identity. Here the determinantabis taken within the extended Neumann subspace.Here comes your footerPage 36
Discussion and Open issues Manifest O(n,n) invariant master action is conjectured by recovering theN- and D-projectors while the orthogonality condition is imposed:where Vol n [Π D ] denotes the O(n, n) covariant volume of the space ofDirichlet projectors, and Reduction to non-double DBI:The double effective DBI-like action can be reduced to theconventional DBI when B=0, but not in the B ≠ 0 case.Here comes your footerPage 37
