Adel Kassaian

摘要:

根据微分算子的系数函数为一系列积分,给出了一元给定次数线性微分算子因果格林函数的一般公式.该解还提供了相应的齐次线性微分方程的基本解作为积分级数的解析式。进一步证明了因果格林函数的乘法性质,并由此给出了几类可分解线性微分算子的因果格林函数的显式表达式.给出了一种由微分算子的系数函数求任意边界条件下给定次数的一般线性微分算子的一元格林函数的方法。

英文摘要:

General formula for causal Green's function of linear differential operator of given degree in one variable is given according to coefficient functions of differential operator as a series of integrals. The solution also provides analytic formula for fundamental solutions of corresponding homogenous linear differential equation as series of integrals. Furthermore, multiplicative property of causal Green's functions is shown and by which explicit formulas for causal Green's functions of some classes of decomposable linear differential operators are given. A method to find Green's function of general linear differential operator of given degree in one variable with arbitrary boundary condition according to coefficient functions of differential operator is demonstrated.
