TY - JOUR AU - Atangana, Abdon AU - Koca, Ilknur PY - 2017 TI - New direction in fractional differentiation JO - Mathematics in Natural Science SP - 18--25 VL - 1 IS - 1 AB - Based upon the Mittag-Leffler function, new derivatives with fractional order were constructed. With the same line of idea, improper derivatives based on the Weyl approach are constructed in this work. To further model some complex physical problems that cannot be modeled with existing derivatives with fractional order, we propose, a new derivative based on the more generalized Mittag-Leffler function known as Prabhakar function. Some new results are presented together with some applications. SN - ISSN 2600-7665 UR - http://dx.doi.org/10.22436/mns.01.01.02 DO - 10.22436/mns.01.01.02 ID - Atangana2017 ER -
