Ultra-relativistic nonthermal power-law ensembles: Cosmic-ray electrons and positron fraction

Tomaschitz, Roman - In: Physica A: Statistical Mechanics and its Applications 394 (2014) C, pp. 110-123

Thermodynamically stable ultra-relativistic power-law distributions are employed to model the recently measured cosmic-ray electron flux and the positron fraction. The probability density of power-law ensembles in phase space is derived, as well as an extensive entropy functional. The...

Harnack inequality on configuration spaces: The coupling approach and a unified treatment

Deng, Chang-Song - In: Stochastic Processes and their Applications 124 (2014) 1, pp. 220-234

In this paper, we establish the dimension-free Harnack inequality on configuration spaces by using the coupling argument. Furthermore, a unified treatment is also used to prove the equivalence between the Harnack inequality on configuration space and that on the corresponding base space under a...
