Birman schwinger operator
WebA remarkable property of the dispersion operators discovered by Z. Lin is that λ>0 is an eigenvalue of the operator Lvor if and only if 0 is an eigenvalue of Aλ; cf. Proposition 3.4. With this fact in mind, we introduce a family of Birman-Schwinger operators, Kλ(µ), which belong to the ideal B2 of Hibert-Schmidt operators and WebMay 3, 2024 · We prove a generalized Birman-Schwinger principle in the non-self-adjoint context. In particular, we provide a detailed discussion of geometric and algebraic multiplicities of eigenvalues of the basic operator of interest (e.g., a Schrodinger operator) and the associated Birman-Schwinger operator, and additionally offer a careful study …
