This analysis demonstrates how D-brane boundary conditions preserve integrability, highlighting conserved charges in the string sigma-model.
A bstract The Coulomb branch of the N = 4 super-Yang-Mills theory is described by a D3-brane in the bulk of AdS 5 × S 5 . We show that the boundary conditions on the D-brane preserve integrability of the string sigma-model by constructing a dynamical and spectral parameter dependent reflection matrix that encodes an infinite number of conserved charges.
