摘 要:
对Boltzman方程的BGK模型,我们证明了,对任意s〉2,如果初始值的s阶矩有限,则其分布解的s阶矩在任何时间区间[0,T]上保持有界。[著者文摘]

Abstract:
For the BGK model of the Boltzman equation,we show that for s 〉 2, the smoments of the distributional solutions remain bounded on any temporal interval [0,T] provided that the moments of order s of the initial data are finite.[著者文摘]
