My relatively short and unpretentious Einführung in die wellenmechanik will be replaced by a treatise in three volumes, each work complete in itself, the first of which is now published."--Pref.
The general plan of the Einführung in die wellenmechanik was preserved inasmuch as the first volume (replacing to some extent the first chapter of the German book) gives a general survey of the whole subject, or a first approach to it, using only elementary mathematics. As can be seen from the Contents, this first volume is fairly complete in itself, covering—although perhaps in a
somewhat superficial way—the entire field of wave mechanics and of the new quantum.
The main object of the second volume is the development of the mathematical ideas which form the most general and most adequate expression of the physical principles embodied in the new mechanics. After a review of the correspondence between the new mechanics and classical mechanics, it will give a thorough presentation of the transformation theory and develop upon this basis the perturbation theory, with some illustrations. This will be followed by a relativistic refinement of the general theory, the investigation of the spin of the electron, and finally, by extensions to problems of many particles and of quantum electrodynamics.
The third volume will give a systematic treatment of various special problems connected with the structure of matter (complex atom, molecules, crystals) and with the radiative and non-radiative interaction between material particles or bodies (collision phenomena, optical effects, and so on).
