Blackbody radiation in nonextensive Tsallis statistics: Exact solution

An exact analysis of n-dimensional blackbody radiation in the recently prop osed nonextensive Tsallis statistics is given here. Thus, the main relation ships of blackbody radiation are generalized in the Tsallis context. In par ticular, it is verified that the relation between pressure, volume, and int ernal energy is form invariant with respect to the nonextensive entropic in dex, q. The results and procedure presented here are expected to be useful in the discussion of nonextensive systems possessing large or infinite numb ers of degrees of freedom. (C) 1998 Elsevier Science B.V.
