In this note we make some remarks concerning Dâ€“metric spaces, and present some examples which show that many of the basic claims concerning the topological structure of such spaces are incorrect,â€¦ (More)

During the sixties, the notion of 2-metric space introduced by GÃ¤hler see 1, 2 as a generalization of usual notion ofmetric space X, d . But different authors proved that there is no relation betweenâ€¦ (More)

The study of metric fixed point theory has been researched extensively in the past decades, since fixed point theory plays a major role in mathematics and applied sciences, such as optimization,â€¦ (More)

and Applied Analysis 3 The purpose of this paper is to generalize the above results using an ICS mapping T : X â†’ X and involving some generalized weak contractions of Boyd-Wong-type 31 . Also, someâ€¦ (More)

In this paper, we introduce some new types of pairs of mappings (f , g) on G-metric spaces called G-weakly commuting of type Gf and Gâ€“R-weakly commuting of type Gf . We obtain also several commonâ€¦ (More)

We prove a coupled random coincidence and a coupled random fixed point theorem under a set of conditions. Our result is a generalization of the recent result of Ä†iriÄ‡ and Lakshmikantham [Stochasticâ€¦ (More)

In this paper, we investigate the accuracy of the Homotopy Analysis Method (HAM) for solving the problem of the spread of a non-fatal disease in a population. The advantage of this method is that itâ€¦ (More)
