摘要:

本文研究了重特征方程的Cauchy问题的唯-性,得出如果μ是整数,则应给m—μ个初始数据;如果μ不是整数,则只需给-个初始数据。

关键词: 重特征方程, 变型算子, 约阶

Abstract:

This paper studies the uniqueness of Cauchy problem for the doubly characteristic equation If μ is an integer, m—μ initial data are necessary so theat we have the uniqueness; if μ is not an integer, one initial datum is enough.

Key words: Doubly characteristic equation, Deformational operator, Restrieted order
