A Tikhonov-type method for inverse source problems for time-space fractional parabolic equations

This paper investigates a Tikhonov-type approach for addressing inverse source problems related to time-space fractional parabolic equations. The method ensures a Hölder-type error estimate for the regularized solution at an optimal order, enabling a fixed parameter choice rule that does not depend on the data. Efficient numerical algorithms are devised for practical implementation, accompanied by numerical examples.
