标题：Scattering Theory for 2 N Parameter Models of Finitely Many Relativistic δ -Sphere and δ -Sphere plus Coulomb Interactions Supported by Concentric Spheres in Quantum Mechanics
摘要：We study scattering theory for 2 N parameter models of finitely many relativistic δ -sphere and δ -sphere plus Coulomb interactions. We provide the mathematical definitions of the Hamiltonians, solve the resolvent equations, and compute the nonrelativistic limits for both models. We obtain new results related to spectral properties and scattering data.
