Birman schwinger operator
Webproperties of the Birman-Schwinger operator arising from our model is quite relevant. In the present note, we show that the Birman-Schwinger operator is Hilbert-Schmidt. We also show that Hλis self-adjoint and bounded from below. In addition, Hλ has a special relation with a kind of two-dimensional contact operator that will be studied in ... WebA general Birman–Schwinger principle and some applications We prove a generalized Birman–Schwinger principle in the non-self-adjoint context and provide a discussion of geometric and algebraic multiplicities of eigenvalues of the basic operator of interest (e.g., a Schrödinger operator) and the associated Birman–Schwinger operator.
