“…We popularize and extends the classic model based on the concept of fractional calculus and the most befitting formula is the iterative fractional integral and differential equations. Many authors have studied this area including (see [1,2,3,4,5,6,7,8,9,10]). The first work in this field was that of E, Eder [11] in 1984, which gave the existence and unique solutions of equation w (τ) = w(w(τ))…”
