The band-structure of one-dimensional Schrodinger operators is calculated when there are (a) high potential barriers (or deep wells), or (b) a wide lattice-spacing (i.e., the distance between minima of the potential). Explicit power-series formulae and error estimates are rigorously proved. The proc
for which the action is finite and stationary under variations, without assuming any additional boundary conditions at infinity. An element of the proof is the vanishing of the stress tensor for a finite action solution, which actually holds true for the general O(N) o-model. For the two-dimensional
