... xn,3.2which implies that F⊂Cn for each n ≥ 1. So, it follows from the definition of Dnthat F ⊂ Dn for each n ≥ 1. Therefore, the sequence {xn} is well defined. Also, from Lemma 2.2 we seethatφxn1,x1 ... condition A3’. Hence, from this point, thecondition A3’ is acceptable. On the other hand, the definition of Dnis of some interest.If Si S for each i 1, 2, ,N1, fi f for each i 1, 2, ... then for x, y ∈ E,φx, y0 if and only if x y. For more details on φ and Π, the readers are referred to 1–4.Let T be a mapping from C into itself. We denote the set of fixed points of T...
