We discuss the basic transport phenomena in gases and plasmas obeying the q-nonextensive velocity distribution (power law). Analytical expressions for the thermal conductivity (Kq) and viscosity (ηq) are derived by solving the Boltzmann equation in the relaxation-time approximation. The...

We investigate the nonextensive q-distribution function for a gas in the presence of an external field of force possessing a potential U(r). In the case of a dilute gas, we show that the power-law distribution including the potential energy factor term can rigorously be deduced based on kinetic...
