TY - JOUR TI - DISCRETE FRACTIONAL DIFFUSION MODEL WITH TWO MEMORY TERMS AU - Qin Yan-Mei AU - Kong Hua AU - Wu Kai-Teng AU - Zhu Xiao-Ming JN - Thermal Science PY - 2015 VL - 19 IS - 4 SP - 1177 EP - 1181 PT - Article AB - Fractional calculus can always exactly describe anomalous diffusion. Recently the discrete fractional difference is becoming popular due to the depiction of non-linear evolution on discrete time domains. This paper proposes a diffusion model with two terms of discrete fractional order. The numerical simulation is given to reveal various diffusion behaviors.
