From Wikipedia, the free encyclopedia
Nyayapathi Venkata Vaikuntha Jagannatha Swamy was a
mathematical physicist . He is well known for his contributions to the physics of
relativistic
harmonic oscillator
[1]
[2]
[3]
[4]
which found wide applications in
Atomic ,
Nuclear and
High Energy Physics . Some of the citations to Swamy's work on the relativistic oscillator are given in references.

[18] A review of the history and the generalized treatment of the relativistic harmonic oscillator is given by Lisboa et al.
[19]
He is also well known for his
group theoretical contributions to mathematical physics. His widely used textbook co-authored with Mark A. Samuel,
"Group Theory Made Easy for Scientists and Engineers" (Wiley-Interscience 1979), was very popular.
L.C. Bidenharn and Swamy published very influential papers on the relativistic
Kepler problem.
[20]
[21] They introduced a symmetric Hamiltonian and solved the Dirac Equation for the Hydrogen atom. The history of this effort is given in
Harold V. McIntosh's website .
Background and career
Swamy received a
BS degree in
Mathematics , a BS and
MS degree in
Physics all from
Bombay University , and a
PhD degree in Physics from
Florida State University . He had lectured at many universities, and was a guest scientist in
Jülich ,
Germany and
Cambridge University in UK. He had served as a professor of physics at
Oklahoma State University until his retirement.
Since his retirement in mid eighties, he used his own funds to visit India and teach at various academic institutions.

Dr Swamy died in his hometown of Visakhapatnam in India on 13 June 2013.
