... In 2012, Samet, Vetro and Vetro introduced α - ψ -contractive mappings and gave some results on a fixed point of the mappings (Samet et al. in Nonlinear Anal. 75:2154-2165, 2012). In fact, their technique ... See full document

... Therefore, T is α ∗ -admissible. Now, we show that T is an α ∗ -ψ-contractive multifunc- tion, where ψ (t) = δt for all t ≥ . If x ∈ / [,  δ ] or y ∈ / [,  δ ], then an easy calculation shows us that α ∗ (Tx, ... See full document

... Further, Mongkolkeha and Kumam [] obtained a common fixed point theorem for pair of compatible mappings satisfying a generalize weak contraction of integral type in modular spaces. Hussain and Salimi [] established ... See full document

... Clearly, δA, B δB, A. For δ{a}, B and δ{a}, {b} we write δa, B and da, b, respectively. We appeal to the fact that δA, B 0 if and only if A B {x} for A, B ∈ BX. Recall that x ∈ X is called a coincidence point resp., ... See full document

... In the article, we introduce a new concept of contraction and prove a fixed point theorem which generalizes Banach contraction principle in a different way than in the known results from the literature. The ... See full document

... On the other hand Berinde [1] introduced a new class of quasi-contractive type operators and proved a strong convergence theorem for Ishikawa iterative process (3) to approximate fixed points in a ... See full document

... It is clear that if 𝑓 is a map which has a fixed point 𝑝 then 𝑝 is also a fixed point of 𝑓 𝑛 for every natural number 𝑛. But the converse is not true, see example [1]. If a map satisfies 𝐹 (𝑓 ) = 𝐹(𝑓 𝑛 ) for each 𝑛 ∈ 𝑁 , ... See full document

... is a contradiction. Therefore fx = gy, i.e. fx = Sx = gy = Ty. Moreover, if there is another point z such that fz = Sz, then by (4) it follows that fz = Sz = gy = Ty, or fx = fz and w = fx = Sx is the unique point of ... See full document

... In 1994, Matthews introduced and studied the concept of partial metric space and obtained a Banach-type fixed point theorem on complete partial metric spaces. In this paper we study fixed point results of new mappings with ... See full document
