Conclusion

Presently there are many applications for determining the Newtonian/Coulomb potentials in theoretical physics. In astrophysics, the need for accurate methods to calculate gravitational fields is ubiquitous. Similarly, physicists require the Coulomb fields in many different types of problems. We have intent to pursue in depth in the future Lie group theoretical implications of these results (Miller 1968, 1972, 1977).

HSC would like to thank (1) the Department of Physics & Astronomy at Louisiana State University (LSU) as well as (2) LSU Prof. Juhan Frank for providing travel and accomodations support for attendance at the 200th IAU symposium on binary star formation in Potsdam, Germany and (3) LSU Prof. Dana A. Browne for his support during the course of this work. ARPR thanks the Alexander von Humboldt Stiftung and Profs. J. Hinze and F. H. M. Faisal of the University of Bielefeld for their hospitality during the course of this work. Thanks to E. G. Kalnins for many inspiring communications and for providing the Moon & Spencer (1961b) reference. Thanks to J. D. Jackson for pointing out the Magnus, Oberhettinger & Soni (1966) reference which gives a further generalization of the Heine identity. Thanks are also due to J. E. Lambert for several subtle grammatical criticisms and suggestions. We acknowledge support from NASA through grant NAG5-8497 and from the NSF through grant AST-9987344. This work also has been supported, in part, by a grant of high-performance computing time on NPACI facilities at the SDSC.
