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 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]. Similarly to the lattice Schro¨dingeroperators and in contrast to the continuous Schro¨din ger operators the family of Friedrichs models h
WebA general Birman–Schwinger principle and some applications We prove a generalized Birman–Schwinger principle in the non-self-adjoint context and provide a discussion of geometric and algebraic multiplicities of eigenvalues of the basic operator of interest (e.g., a Schrödinger operator) and the associated Birman–Schwinger operator.
