线性偏微分方程问题的微分算子解
摘要
用微分算子法给出了线性扩散方程和波动方程的通解及初值以及边值相关问题的算子解
特别是对非齐次方程和非齐次边界问题处理尤其简捷适用.同时
此法也很好地克服了行波法、分离变量法与积分变换法等方法计算的繁锁
成为一种简便易记计算十分简单的解决问题的方法.
Abstract
General solution expression of linear partial diferential equations is given by diferential operators. And the solution of problem with initial and boundary conditions is obtained by writing the expression. The method is convenient to be used
especially to nonhomogeneous equations and nonhomogeneous boundary value problem. It has become a general method.
