@inproceedings{Adami2009ExistenceOD, title={Existence of Dynamics for a 1 − d NLS equation perturbed with a generalized point defect}, author={R. Adami and D. Noja}, year={2009} }

In the present paper we study the well-posedness for the one-dimensional cubic NLS perturbed by a generic point interaction. Point interactions are described as the 4-parameter family of self-adjoint extensions of the symmetric 1D Laplacian defined on the regular functions vanishing at a point, and in the present context can be interpreted as localized defects interacting with the NLS field. A previously treated special case is given by an NLS equation with a δ defect which we generalize and… Expand
