Özet

First, we define a new class of Caputo fractional differential equations of order 3 < ȷ ≤ 4. Then, we show that m2(ϕ) is a Banach space, and we define a new Hausdorff measure of noncompactness (MNC) in this space. Then, by the new MNC, we discuss the existence of solutions of infinite systems of a new class of fractional differential equations in double sequence space m2(ϕ). Finally, we present an example to show the efficiency of our results
