Geometric parametrices and the many-body Birman-Schwinger principle
The spectral properties of N-body Schrödinger operators are studied using the resolvent equations of Fredholm type and certain geometric constructions. The estimation of the number of bound states are given and effectively applied for certain short-range interactions. The exponential bounds on eigenfunctions are discussed also.
