Fractional Order Tikhonov Regularization Method for Solving a Class of Time Fractional Order Inverse Diffusion Problems
摘要
Abstract
We discussed a class of inverse problem of time fractional order diffusion equations by using the fractional order Tikhonov regularization method.We gave selection criteria for the regularization parameter under prior and posterior conditions,and gave rigorous proofs of the convergence of the method.Numerical experimental results show that the fractional order Tikhonov regularization method is effective in solving this problem.关键词
