Since that time thousands of articles have been published on the subject, mostly about the domain of small g? (weak coupling regime), although physics corresponds to g? ~ 1, and they were mostly about energies.This book is focused on studying eigenfunctions as a primary object for any g?. Perturbation theory in g? for the logarithm of the wavefunction is matched to the true semiclassical expansion in powers of ?: it leads to locally-highly-accurate, uni
