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 … WebBaird & Warner. May 2024 - Present1 year. Chicago, Illinois, United States.

We consider ve di erent operators, three of them discrete and two continuous. Discrete operators are as follows: Schr odinger operator de ned on Z + with a complex potential, Schr odinger operator de ned on Z with a complex potential, and a Dirac operator de ned on Z, also with a complex potential.
