The Klein–Fock equation, proper-time formalism and symmetry of the hydrogen atom

Abstract

We present main points of some of Fock papers in Quantum Theory, which were not properly followed when published. IntroductionFock papers on Quantum Theory have quite different lifes in Physics. Some of them were immediately recognized with Fock name attached to them. Hartree-Fock approach, Fock space and Fock representation are very well known examples. Another ones were not properly used when published. To this class belong papers where Fock was ahead of time, and his comptemporaries were not able to really understand their importance. Klein-Fock equation, proper-time formalism and symmetry of Hydrogen atom are best examples of Fock papers within such a class.In this lecture we explain main points of these Fock papers and remind Fock interpretation of energy-time uncertainty relation, as well as his ideas on generalization of the concept of physical space published in his last paper.
