摘要
本文介绍了余法分布空间上的仿微分算子T_1与仿复合X~*的基本性质,导出了拟线性偏微分方程的奇性传播模型,并对其解u以及相应特征面X的正则性给出了证明。
This paper introduces the basic properties of pare-differential operator T_l and pare-composition X~* on the spaces of conormal distributions and derives a model of the singularity propagation of quasilinear partial differential equations. The regularity of the solution u with respect to the characteristic surface X is presented.
