Unique inversion of orders and potential for multi-term time fractional wave equations
The paper investigates an inverse problem of determining the orders and potential function of multi-term time fractional wave equations. By analyzing the asymptotic behavior of the multivariate Mittag–Leffler function, we show the uniqueness of the inverting the orders and potential term using interior domain measurement data. The article also provides numerical simulations, showing how to handle noisy data and reconstruct the parameters of the equation through Tikhonov regularization.
