TY - JOUR TI - General fractional calculus operators containing the generalized Mittag-Leffler functions applied to anomalous relaxation AU - Yang Xiaojun JN - Thermal Science PY - 2017 VL - 21 IS - 11 SP - 317 EP - 326 PT - Article AB - In this paper, we address a family of the general fractional calculus operators of Wiman and Prabhakar types for the first time. The general Mittag-Leffler function to structure the kernel functions of the fractional order derivative operators and their Laplace integral transforms are considered in detail. The formulations are as the mathematical tools proposed to investigate the anomalous relaxation.
