WebJan 1, 2024 · Recalling (5.8), we conclude that the maximum of the quantities on the right-hand-sides of (5.9) and (5.10) dominates the operator norm of the Birman-Schwinger operator K (λ) and the result immediately follows from the Birman-Schwinger principle as in the proof of Theorem 2. 5.6. Proof of Theorem 4. First we establish an auxiliary lemma.
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 …
