变系数线性偏微分方程的边值问题

Boundary Value Problems for Linear PDEs with Variable Coefficients

A. S. Fokas

摘要:

提出了一种研究一类{ \it变}系数线性偏微分方程边值问题的新方法。该方法是基于作者最近提出的研究具有{ \it常数}系数的偏微分方程边值问题的思想。作为说明性的例子,解决了下列边值问题:(a)射线上的Dirichlet和Neumann问题的时间相关的薛定谔方程与空间相关的潜力。(b)拉普拉斯方程变系数推广的四分之一平面上的庞加莱问题。

英文摘要:

A new method is introduced for studying boundary value problems for a class of linear PDEs with {\it variable} coefficients. This method is based on ideas recently introduced by the author for the study of boundary value problems for PDEs with {\it constant} coefficients. As illustrative examples the following boundary value problems are solved: (a) A Dirichlet and a Neumann problem on the half line for the time-dependent Schrödinger equation with a space dependent potential. (b) A Poincaré problem on the quarter plane for a variable coefficient eneralisation of the Laplace equation.
