Abstract

This research studies the inverse boundary value problem for fractional elliptic equation of Tricomi–Gellerstedt–Keldysh type and obtains a condition stability result. To recover the continuous dependence of the solution on the measurement data, a generalized Tikhonov regularization method based on ill-posedness analysis is constructed. Under the a priori and a posterior selection rules for the regularization parameter, corresponding Hölder type convergence results are obtained. On this basis, this thesis verifies the simulation effect of the generalized Tikhonov method through numerical examples. The examples show that the method performs well in dealing with the problem under consideration.

分式椭圆方程反边界值问题的广义提霍诺夫正则化方法
本研究研究了 Tricomi-Gellerstedt-Keldysh 型分式椭圆方程的逆边界值问题,并获得了条件稳定性结果。为了恢复解对测量数据的连续依赖性,构建了一种基于失当分析的广义 Tikhonov 正则化方法。在正则化参数的先验和后验选择规则下,得到了相应的赫尔德型收敛结果。在此基础上,本论文通过数值实例验证了广义 Tikhonov 方法的模拟效果。实例表明,该方法在处理所考虑的问题时表现良好。

期刊介绍: The main aim of Boundary Value Problems is to provide a forum to promote, encourage, and bring together various disciplines which use the theory, methods, and applications of boundary value problems. Boundary Value Problems will publish very high quality research articles on boundary value problems for ordinary, functional, difference, elliptic, parabolic, and hyperbolic differential equations. Articles on singular, free, and ill-posed boundary value problems, and other areas of abstract and concrete analysis are welcome. In addition to regular research articles, Boundary Value Problems will publish review articles.
