摘要/Abstract

摘要：

This article investigates the fractional derivative order identification, the coef-ficient identification, and the source identification in the fractional diffusion problems. If 1 < < 2, we prove the unique determination of the fractional derivative order and the dif-fusion coefficient p(x) by R t0 u(0, s)ds, 0 < t < T for one-dimensional fractional diffusion-wave equations. Besides, if 0 < < 1, we show the unique determination of the source term f(x, y) by U(0, 0, t), 0 < t < T for two-dimensional fractional diffusion equations. Here, denotes the fractional derivative order over t.
