WebMay 19, 2014 · Download PDF Abstract: We study several natural multiplicity questions that arise in the context of the Birman-Schwinger principle applied to non-self-adjoint operators. In particular, we re-prove (and extend) a recent result by Latushkin and Sukhtyaev by employing a different technique based on factorizations of analytic … WebUNIFORM BOUNDS OF DISCRETE BIRMAN-SCHWINGER OPERATORS YUKIHIDE TADANO AND KOUICHI TAIRA Abstract. In this note, uniform bounds of the Birman-Schwinger operators in the discrete setting are studied. For uniformly decaying potentials, we obtain the same bound as in the continuous setting. However, for non-uniformly

WebJan 1, 2024 · Furthermore, in general the operator K z defined in (4.1) is a bounded extension of the classical Birman–Schwinger operator A (H 0 − z) − 1 B ∗ defined on dom (B ∗). Since in our case the initial domain of B ∗ is C 0 ∞ (R n; ℂ N), hence dense in ℌ, we get that K z is exactly the closure of A (H 0 − z) − 1 B ∗.
