摘要
H.Urgu在[1]中给出了一类弱双曲算子哥西问题适定的充分与必要条件.本文给了另一个充要条件,并证明这两个条件是等价的。
In this paper; we shall deal with well-posedness of the Cauchy problem for some
weakly hyperbolic operators with non-involutive mulhple Characteristics. For these operators, The
Conditions of sufficient and necessary on the well-posedness are obtained.
