As particular examples, we consider the electron-phonon interaction and the interaction between localized and conduction electrons. The theory is applied to explain a non-monotonic variation of the out-plane resistivity with temperature observed in quasi-two-dimensional metals.14 pages, 5 figuresStrongly Correlated ElectronsMesoscale and Nanoscale Physicstext
