It serves as a trial system or zero-level approximation in many sophisticated methods of polaron investigation. This book analyzes, in particular, the possibility of reduction of the full polaron Hamiltonian to the linear one, and introduces a special method of calculating thermodynamical characteristics based on the calculation of the averages of T-products. This T-product formalism seems to be a more convenient way of doing similar calculations involving Feynman's path integral approach.Thi 606 $aPolarons 606 $aElectrons 615 0$aPolarons. 615 0$aElectrons. 676 $a539.7/2112 700 $aBogolubov$b N.
