“…The convergence order of iterative methods, in general, was obtained using Taylor expansions and conditions on high order derivatives not appearing on the method. These conditions limit the applicability of the methods [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22]. For example: Let X = Y = R, Ω = [− 1 2 , 3 2 ].…”
