Hyers–Ulam and Hyers–Ulam–Rassias Stability of First-Order Nonlinear Dynamic Equations
We investigate Hyers–Ulam and Hyers–Ulam–Rassias stability of first-order nonlinear dynamic equations for functions defined on a time scale with values in a Banach space.

Open AccessOn fixed point theory in topological posets, extended quasi-metric spaces and an application to asymptotic complexity of algorithms
In this paper we present a few fixed point results in the framework of topological posets. To this end, we introduce an appropriate notion of completeness and order-continuity. Special attention is paid to the...

Open AccessProjective contractions, generalized metrics, and fixed points
In 1981, Borsík and Doboš studied the aggregation problem for metric spaces. Thus, they characterized those functions that allow one to merge a collection of metrics providing a single metric as a result (Bors...

A primal-dual method of partial inverses for composite inclusions
S**arn’s method of partial inverses has found many applications in nonlinear analysis and in optimization. We show that it can be employed to solve composite monotone inclusions in duality, thus opening a ne...

Open AccessMetric fixed point theory for nonexpansive map**s defined on unbounded sets
It is standard practice in metric fixed point theory to reduce fixed point questions for map**s defined on unbounded sets to the bounded case. Many of these results are couched in a Banach space framework an...

Open AccessThe implicit midpoint rule for nonexpansive map**s
The implicit midpoint rule (IMR) for nonexpansive map**s is established. The IMR generates a sequence by an implicit algorithm. Weak convergence of this algorithm is proved in a Hilbert space. Applications t...

Open AccessFixed point theorems in generalized metric spaces with applications to computer science
In 1994, Matthews introduced the notion of a partial metric space in order to obtain a suitable mathematical tool for program verification (Matthews in Ann. N.Y. Acad. Sci. 728:183-197, 1994). He gave an appli...

Open AccessG-β-ψ contractive-type map**s and related fixed point theorems
In this paper, we introduce the notion of generalized G-β-ψ contractive map**s which is inspired by the concept of α-ψ contractive map**s. We showed the existence and uniqueness of a fixed point for such mapp...
