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 …

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 ... WebMar 2, 2024 · In the recent paper [32] the authors have considered the Birman-Schwinger (Cwikel) type operators in a domain Ω ⊆ R, having the form TP = A∗PA. Here A is a pseudodifferential operator in Ω of order −l = −N/2 and P = V μ is a finite signed measure containing a singular part. We found out there that for such operators, properly defined …
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]).
