Vector NLS solitons interacting with a boundary*

We construct multi-soliton solutions of the n-component vector nonlinear Schr\odinger equation on half-line subject to two classes integrable boundary conditions (BCs): homogeneous Robin BCs and mixed Neumann/Dirichlet BCs. The construction is based approach dressing BCs: soliton are generated in preserving at each step Darboux-dressing process. Under BCs, examples, including boundary-bound solitons, explicitly derived; under can act as a polarizer that tunes different components solitons.
