Based on a survey of the appropriate literature and on separate investigations concerning distributions of asset lives and depreciation patterns of vehicles, gross and net capital stocks as well as depreciation at constant prices and at replacement cost have been estimated for Austria using the...

A cluster series is established for the cooperative Jahn-Teller-T-e and theT-t-systems in the simple cubic and square lattices. We calculate the phase transition temperature Tc, the specific heat and the “susceptibility” in zero order and in 2-site cluster approximation. Additionally in the...

We are concerned with the phase transition behaviour of the cooperative Jahn-Teller T-e system and the T-t system in a simple cubic lattice. High temperature series expansions are derived for the specific heat and the elastic constants. In the latter case the symmetry has to be broken by...
