奇异核存在下麦克斯韦分子齐次玻尔兹曼方程的数学处理

Mathematical treatment of the homogeneous Boltzmann equation for Maxwellian molecules in the presence of singular kernels

Emanuele Dolera

摘要:

本文证明了当初始数据选自R^3上具有有限二阶矩的所有Borel概率测度空间,且碰撞核(角)满足一个很弱的截断条件时,麦克斯韦分子空间齐次Boltzmann方程弱解的存在性.动量和能量守恒也证明了这些弱的解决方案,而不诉诸任何有界的熵。

英文摘要:

This paper proves the existence of weak solutions to the spatially homogeneous Boltzmann equation for Maxwellian molecules, when the initial data are chosen from the space of all Borel probability measures on R^3 with finite second moments and the (angular) collision kernel satisfies a very weak cutoff condition. Conservation of momentum and energy is also proved for these weak solutions, without resorting to any boundedness of the entropy.
