Derivative Corrections from Boundary State Computations

The boundary state formalism is used to confirm predictions from non-commutativity for the derivative corrections to the Dirac-Born-Infeld and Chern-Simons actions, at all orders in derivatives. As anticipated by S. Mukhi, the method applies by induction to every coupling in the Chern-Simons action. It is also used to derive the corrections to the Dirac-Born-Infeld action at quadratic order in the field strength.
