我们将考虑P = (tDt) +∑m−1 j=0∑|α|≤m−j j,α(t, z)·(μ(t)Dz) (tDt) j的线性Fuchsian偏微分算子。对于这类算子,我们将给出比Baouendi和Goulaouic在1973年得到的存在唯一性定理稍一般一些的存在唯一性定理。我们将指定函数μ(t)的一些性质,并断言一个性质是定理成立所必需的。
We will consider linear Fuchsian partial differential operators of the form P = (tDt) + ∑m−1 j=0 ∑ |α|≤m−j aj,α(t, z) · (μ(t)Dz) (tDt) j . For this class of operators, we will formulate existence and uniqueness theorems which are slightly more general than the ones obtained by Baouendi and Goulaouic in 1973. We will specify some properties of the function μ(t) and assert that a property is necessary for our theorems to hold.
