Abstract :
Summary form only given, as follows. The present paper shows that the equations of state PV/sup 4/3/=const, TV/sup -4/3/P/sup 1/3/=const and PV=E/3 cannot be valid simultaneously for the adiabatic change of state of a photon gas. Furthermore, the Planck´s distribution-and so Wien´s law and the Rayleigh-Jeans connection as well-cannot be invariant in case of adiabatic change of state of a photon gas. Namely, in case of adiabatic change of state of photon gas, a new type of ultraviolet catastrophe appears. The cause of these contradictions can be the lack of longitudinal magnetic flux density B/sup (3/) in the usual description. These results are of fundamental importance in the case of arbitrary deformation of electromagnetic radiation fields or quantum plasmas.
