Summary, etc. The current state of polaron theory as applicable to transition metal oxides is reviewed, including problems such as impurity conduction where disorder plays a role. An estimate is given of the conditions under which polaron formation leads to an enhancmnent of the mass but no hopping energy. The binding energy of a polaron to a donor or acceptor in narrow- band semiconductors is discussed. The experimental evidence about the conductivity of TiO2 and NiO is reviewed. Impurity conduction in NiO and conduction in glasses containing traDsition metal ions is discussed and it is emphasized that the activation energy for hopping nearly all vanishes at low temperatures. Pollak's theory of a.c. impurity conductivity is reviewed and applied to the problem of dielectric loss in these materials.
