Irreversible thermodynamics in the framework of Tsallis entropy

The symmetry of the kinetic Onsager coefficients is proved in the context of Tsallis generalization of Boltzmann-Gibbs statistics. A generalized Nyquist theorem is also introduced. The analysis of the noise spectrum of the thermodynamics fluctuation is presented in the framework of Tsallis entropy. A comment about the spectrum 1/ƒν, in connection with non-Gaussian statistics, is also discussed.
