Comments D-brane configurations are specified by Π N (or equiv. Π D ), by solving thoseconditions. The boundary conditions specified by Π N and Π D describe a T-dualized D-brane pair. There are many solutions (i.e. D-brane configurations) whose physicalinterpretations are subtle. Orthogonality is imposed for physical reasons. It simplifies the calculation,but also excludes some simple configuration such as {D2 / D0} pair withnon-vanishing B-field.Here comes your footerPage 22
Examples: n=2 case D-brane pairD0-D2 pair: Consider the Dirichlet projectorwhich gives rise to the Neumann b.c.after imposing the self-duality constraint the b.c. becomes(D0-brane in {X,Y})or (D2-brane in{~X ,YY~})~One can T-dualize {X,Y} and { X , Y~ } s.t. the D2 in physical space is producedbySimilar case for the D1-D1 pair.Here comes your footerPage 23
