The exact Green function of a relativistic Coulomb system via the transformation method
2000
Journal of Physics A: Mathematical and General
Preserved Fulltext
The exact Green function of a relativistic Coulomb system is given by the transformation method. The earlier treatments are based on the multiple-valued transformation of Kustaanheimo and Stiefel as well as the perturbation expansions. The method presented in this paper relates the relativistic Coulomb path integral to the simple ones and may apply to a large class of problems.
