Abstract.
For the pair \(-\Delta,-\Delta-\alpha\delta_\mathcal{C}\) of self-adjoint Schröodinger operators in \(L^2(\mathbb{R}^n)\) a spectral shift function is determined in an explicit form with the help of (energy parameter dependent) Dirichlet-to-Neumann maps. Here δC denotes a singular δ-potential which is supported on a smooth compact hypersurface \( { C}\subset(\mathbb{R}^n)\) and δ is a real-valued function on C.
