Summary

It gives a detailed and rigorous exposition of the WKB method in one dimension and its exact version, which includes nonperturbative effects in the Planck constant. This is illustrated in many examples, including the double-well potential. It also includes a description of the semiclassical quantization of higher-dimensional integrable systems, which are illustated by the Toda lattice.
