Abstract
In discussing the solution of the Schrödinger equation (4.1), we have so far simply treated V(r) as a known periodic function of r. But in fact, the choice of V(r) is itself a subtle and difficult problem, because (4.1) is only an approximation to a much more complicated equation, and V(r) has to be chosen in such a way as to make the approximation as good as possible. It is worth looking briefly at this more complicated equation, just to see what approximations are needed in order to reduce it to the soluble form (4.1).
