On v^ 2/c^ 2 expansion of the Dirac equation with external potentials
... A semirelativistic expansion of the Dirac equation ( up to v 2 /c2 terms ) is treated in almost all sources on quantum mechanics which include elements of the relativistic quantum theory. This expansion is of importance for problems involving electric and magnetic potentials for which exact solution ...

The functions were hardly be interpreted as transitions; the Fourier coefficients were oscillating even if the exciting frequency equaled the proper one perfectly. ...

Exponential complexity and ontological theories of quantum

Effective Field Theory of General Relativity

But all gravity interactions are suppressed by MPl2 - relative effect could then be much bigger ~O(1)? - small violations of unit ...
