- Abstract
-
A backward problem for composite fractional relaxation equations is considered with Caputo's fractional derivative. Based on a spectral problem, the representation of solutions is established. Next, we show the mildly ill-posedness in the Hadamard sense. Afterthat, we show the regularization solution by two regularization methods : the Landweber regularization method and the iterative method. Afterthat, the convergent rate between the exact solution and the regularized solution is provided, under the a priori parameter choice rule.
