Abstract |
|
Dutta and Choudhury [1] proved the following result: If (X, d) is a complete metric space and T : X→X a self-mapping satisfying the inequality Ψ(d(Tx, Ty))≤ ψ(d(x, y)−φ(d(x, y) where ψ, φ : [0,∞) →[0,∞) are both continuous and monotone non-decreasing functions with ψ(t)= φ(t) = 0 if and only if t = 0. Then T has a unique ï¬xed point. In this paper, we have proved that if we do not assume the conditions of continuity on both ψ and φ, still the result is valid. |
