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 … WebDec 15, 2024 · A standard trick (a form of the Birman-Schwinger principle) enables us to carry over the eigenvalue estimates in Theorem 3.3 to the case of operator acting in the …

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 ∗. WebWe remind the reader that the positive integral operator on the right hand side of equation (2.7) is the renowned Birman-Schwinger operator, widely used in the literature on small pertur-bations of the Laplacian in the sense of quadratic forms, and that the two integral operators are isospectral (see [13], [14]). Webtwo-particle Schro¨dinger operators have been studied in [4, 7, 14, 18, 17, 28, 29, 32] and have been applied to the proof of the existence of Efimov’s eff ect in [4, 18, 28, 29, 31].
