A generalized Birman-Schwinger principle and applications to one-dimensional Schrödinger operators with distributional potentials

Fritz Gesztesy, Roger Nichols

Given a self-adjoint operator $H_0$ bounded from below in a complex Hilbert space $\mathcal{H}$, the corresponding scale of spaces $\mathcal{H}_{+1}(H_0) \subset \mathcal{H} \subse…
