Tóm tắt
In this paper, we investigate the problem of backward heat equations with time-dependent coefficient in the Banach space L_p(R), p>1. For this problem, we first prove the stability estimates of Hölder type. After that the Tikhonov-type regularization is applied to solve the problem. A priori and a posteriori parameter choice rules are investigated, which yield error estimates of Hölder type. Numerical implementations are presented to show the validity of the proposed scheme.
