The Klein-Gordon-Fock theory as a one-particle relativistic quantum mechanics
The paper attempts to show that Klein-Gordon-Fock (KGF) theory, a relativistic equation for scalar bosons, can be recast as a single-particle quantum mechanics problem. It achieves this by developing a two-stage formalism: first using two-component spinors and then mapping the results onto a simpler one-component wave function. This connects the complex relativistic wave equations to standard quantum mechanical frameworks.
