Abstract
Construction of integrable field theories in space with a boundary is extended to fermionic models. We obtain general forms of boundary interactions consistent with integrability of the massive Thirring model and study the duality equivalence of the MT model and the sine-Gordon model with boundary terms. We find a variety of integrable boundary interactions in the Gross-Neveu model from the boundary supersymmetric sine-Gordon theory by using boson-fermion duality.
