Abstract
The partition function of the periodic Anderson model is expressed via the path integral over ''slow'' localized d-electron variables and th ose of ''light'' conduction s-electrons. The temperature-dependent d-e lectron structure is derived. The energy shift of the d-electron level demonstrates the Kondo-like temperature logarithm. At low temperature a Hubbard-like behaviour of d-electrons is found.
