“…This new ABC derivative has a great memory due to the existence of Mittag–Leffler function as its nonlocal kernel; eventually, it results in a better comparative performance as compared to other existing fractional derivative operators. Validation of the above claim is justified by applying ABC operator, instead of other operators, and solving various scientific models, namely, the general sequential hybrid class of FDEs [15, 16], controllability of neutral impulsive [17], Covid‐19 mathematical model [18, 19], fractional typhoid model [20], wireless sensor network as an application of the fuzzy fractional SIQR model [21], plasma particle model with circular LASER light polarization [22], Hepatitis B model [23], SEIR and blood coagulation technologies [24], a fractal‐fractional tuberculosis [25] and tobacco [26] mathematical model, a class of population growth model [27], and the fractional nonlinear logistic system [27].…”
