The behaviour of boundary conditions under relevant bulk perturbations is studied for the Virasoro minimal models. In particular, we consider the bulk deformation by the least relevant bulk field which interpolates between the m and (m − 1) unitary minimal model. In the presence of a boundary this bulk flow induces an RG flow on the boundary, which ensures… (More)
