## Schrödinger equation

Sorry to revert but where did this equation come from? Is it in a reliable secondary source? If you derived it, we cannot allow original research. Wikipedia is an encyclopedia which summarizes what others have written from as reliable references as possible. Thanks for understanding, M∧Ŝc2ħεИτlk 18:12, 5 April 2014 (UTC)

Sorry to revert again, but it seems you derived the "relativistic Schrödinger equation" from the incorrect equation:
${\displaystyle E={\sqrt {(pc)^{2}+(mc^{2})^{2}}}-mc^{2}+V}$
with m the rest mass. If the particle is not in a potential, its total energy is:
${\displaystyle E={\sqrt {(pc)^{2}+(mc^{2})^{2}}}}$
If the particle is in a potential, the subtraction of the scalar potential energy V from the total energy of the particle E to give:
${\displaystyle E-V={\sqrt {(pc)^{2}+(mc^{2})^{2}}}}$
is correct (an example is the minimal coupling of an electric potential φ in the Klein-Gordon equation with zero magnetic potential A), but why subtract the rest mass-energy? The mass-energy of the particle is included under the root and is important! (see four vector)
Again, what you are calling the "Relativistic Schrödinger equation" is not published in the literature, so it is out of place on WP. What is in the literature, and has been studied, is the Klein-Gordon equation. It seems you are trying to do something similar, but is flawed at the beginning.
Also, you had red links to Relativistic Schrödinger equation and Relativistic Energy Conservation. Were you intending to create these articles? There are loads on relativistic mass-energy and its conservation in many particle systems, see for example mass-energy equivalence, relativistic energy-momentum relation, and relativistic mechanics.
