Instead of electric charge, as the basic substance of EM theory, its static potential, as some energetic fluid, in the dielectric, non-resistive and reactive medium, is here taken as the starting quantity. All the remaining EM quantities are thus defined in the succession, by the...

By imposing a particular constraint of solvability on the Liouville normal form of the BenDaniel-Duke type variable mass Schr¨odinger equation, we have derived a class of solvable potentials and harmonic oscillator type solutions for the system. The method has been shown to be ap...
