Boltzmann-type equations with inelastic interactions appear as kinetic models for rapid flows of granular media. Among many interesting features of solutions of such equations is non-Gaussian behavior of the high-energy tails of velocity distributions. I will present recent work with I. Gamba, A. Bobylev and C. Villani on rigorous derivation of this high-energy behavior. A novel technique for obtaining pointwise estimates for the nonlinear Boltzmann equation, based on a comparison principle, will receive particular attention.
