Analysis and discretization to fractional derivative

problems with (hidden memory) variable order

 要:

We study variable-order fractional derivative problems with and without hidden memory. The well-posedness of the models and the smoothing properties of their solutions are proved, based on which the corresponding fully-discrete finite element methods are analyzed. Numerical experiments are carried out to substantiate the theoretical findings.
