“…The forward problem with nonlocal differential version gives us the models appearing in mathematical physics in the context of anomalous diffusion ones, fluid flow through porous media; see, e.g. [1,10,11,16,29,21,23,26]. We would like also to emphasize that, in constract to the local differential model, which the derivative can be determined by observations in the neighboorhoods, the nonlocal differential equations can be obtained from the observations in the whole of the interests.…”
