Birman schwinger operator

WebIn particular, we provide a detailed 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, and additionally offer a careful study of the associated Jordan chains of generalized eigenvectors of both operators. 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
