Regularity of the Inelastic Kac Equation
【摘要】 研究Kac-Boltzmann型方程,建立了碰撞核的Povzner型不等式和碰撞算子的L~p估计,得到了方程的正解的加权L~p估计.在此基础之上证明了解的光滑性.
【Abstract】 We study the Kac-Boltzmann equation.Firstly,the Povzner inequality for the collision kernel and the L~p estimates for the collision operator are established. Secondly,we obtain some weighted L~p estimates for positive solutions to the equation. With these estimates,the smoothness of the solutions is proved.
