摘要
文章对半线性弹性动力学方程组的初值奇性传播问题建立了余法分布空间,然后讨论了该空间的一些基本性质,最后得到了该空间的拟微分算子与两个二阶微分算子可进行交换运算的结果。这对于在余法分布框架下研究半线性弹性动力学方程组的初值奇性传播问题是很重要的。
In this paper, we construct conormal distribution spaces on the propagation of initial singularities for semilinear elastic dynamical system, then discuss the character of the spaces, and last prove the theorems of exchange operation which are conducted by pseudo-differential operators in the conormal distribution spaces and two second-order differential operators, this is very important for deeply studying the propagation of initial singularities for semilinear elastic dynamical system in the conormal distribution spaces.
