一奇异偏微分方程关于某单项式1-Gevrey的形式解的研究

On Monomially 1-Gevrey Formal Solution of a Singular Partial Differential Equation

通过比较系数法验证某一奇异偏微分方程存在惟一形式幂级数解,证明此形式幂级数解关于某单项式是1-Gevrey的.

We can use the method of comparing coefficient to find out the unique formal power series solution of a singular partial differential equation and proof that the formal power series solution is 1-Gevrey in some monomials.
