Rejection of the Light Quantum: The Dark Side of Niels Bohr
Luis J. Boya
Evidence is recalled of the strong opposition of Niels Bohr, at the time of the Old Quantum Theory 1.913-25, to the Lichtquanten hypothesis of Einstein. Some episodes with H.A. Kra…
Problems in Lie Group Theory
L. J. Boya
The theory of Lie groups and representations was developed by Lie, Killing, Cartan, Weyl and others to a degree of quasi-perfection, in the years 1870-1930 >. The main topological…
Volumes of Compact Manifolds
Luis J. Boya, E. C. G. Sudarshan, Todd Tilma
We present a systematic calculation of the volumes of compact manifolds which appear in physics: spheres, projective spaces, group manifolds and generalized flag manifolds. In each…
Graphical and Kinematical Approach to Cosmological Horizons
L. J. Boya, M. A. Per, A. J. Segui
We study the apparition of event horizons in accelerated expanding cosmologies. We give a graphical and analytical representation of the horizons using proper distances to coordina…
