In this paper, we deal with a Sturm-Liouville problem which has discontinuity at one point and contains an eigenparameter in a boundary condition. We obtain a regularized trace formula for the problem.

Keywords: Regularized trace formula, Gelfand-Levitan trace formula, discontinuous eigenvalue problem
