“…Remark As is in Mustafa, we present the following: - (1)From assumption (A.1) we deduce that and assumption (A.2) implies that there exists t 0 > 0 such that The nonincreasing property of g implies that Continuity of G on [0, r ] yields, for some constants a , b > 0 Consequently, for any t ∈ [0, t 0 ], we have and, hence,
