Lưu Trích dẫn Chia sẻAbstract
In the present paper, we study the initial inverse problem (backward problem)for a two‐dimensional fractional differential equation with Riemann‐Liouvillederivative. Our model is considered in the random noise of the given data.We show that our problem is not well‐posed in the sense of Hadamard. A trun-cated method is used to construct an approximate function for the solution(called the regularized solution). Furthermore, the error estimate of the regu-larized solution in L2and Hτnorms is consi dered and illustrated by numericalexample
