高维Helmholtz方程柯西问题的磨光化方法
A mollification method for the Cauchy problem for theHelmholtz equation in multi-dimensional case
摘要
Abstract
A Cauchy problem for the Helmholtz equation is discussed in multi-dimensional case at fixed frequency.This problem is an inverse problem and is severely ill-posed,its solution does not depend continuously on the measuring data.The error estimation between the exact solution and regularized approximate solution of this problem is obtained by use of the mollification method.关键词
