### Unique Common Fixed Point Theorem For Weakly Compatible Mappings In Digital Metric Space

Fixed point theory ends in masses of packages in mathematics, computer technological, engineering, game concept, fuzzy principle, image processing and so on. In metric areas, this theory starts with the Banach fixed-point theorem which gives a optimistic technique of locating constant factors and an crucial device for solution of some issues in mathematics and engineering and consequently has been generalized in lots of methods. A foremost shift inside the area of fixed point idea got here in 1976, when Jungck 7, 8, 9, defined the idea of commutative and compatible maps and proved the common fixed point results for such maps. Later on, Sessa 15 gave the idea of weakly compatible, and proved results for set valued maps. Certain altercations of commutativity and compatibility can also be found in 5 7 15 16 . In this paper we establish a unique common fixed point theorem satisfying the pairs of weakly compatible mappings in the context of digital metric space. An example is given in the support of our main result.

### Common fixed point theorems for four weakly compatible mappings using CLRg property

The first important result on fixed-point for contractive-type mappings was the well-known Banach fixed point theorem, published for the first time in 1922. In 1998, Jungck and Rhoades [10] introduced the notion of weakly compatible mappings and showed that compatible maps are weakly compatible but not conversely. The concept of fuzzy set was introduced by Zadeh [20] and after his work there has been a great endeavor to obtain fuzzy analogues of classical theories. In 1994, George and Veeramani [5] introduced the notion of fuzzy metric space and

### Some Common Fixed Point Theorems for Weakly Compatible Mappings in Metric Spaces

We establish a common fixed point theorem for weakly compatible mappings generalizing a result of Khan and Kubiaczyk 1988. Also, an example is given to support our generalization. We also prove common fixed point theorems for weakly compatible mappings in metric and compact metric spaces.

### Common coupled fixed point theorems for weakly compatible mappings in fuzzy metric spaces

### Coupled Fixed Point Theorem for Weakly Compatible Mappings in Intuitionistic Fuzzy Metric Spaces

The aim of present paper is to introduce the notion of t- conorm of H-type analogous to t-norm of H-type introduced by Hadzic [9] and using this notion we prove coupled fixed point theorems for weakly compatible mappings in intuitionistic fuzzy metric spaces.

### Coupled fixed point theorems for occasionally weakly compatible mappings in fuzzy metric space

results by proving the existence and uniqueness of the solution for a periodic boundary value problem. Later these results were extended and generalized by Sedghi et al. [9], Fang [2] and Xin-Qi Hu [10] etc. Fixed point theorems, involving four self-maps, began with the assumption that they are commuted. Sessa [8] weakened the condition of commutativity to that of pairwise weakly commuting. Jungck generalized the notion of weak commutativity to that of pairwise compatible [4] and then pairwise weakly compatible maps [5]. Jungck and Rhoades [6] introduced the concept of occasionally weakly compatible maps. In this paper we introduce some coupled fixed point theorems for occasionally weakly compatible mappings in fuzzy metric space.

### Fixed Point Theorems for Occasionally Weakly Compatible Mappings in Semi-Metric Space

The fixed point theory has become a part of non-linear functional analysis since 1960. It serves as an essential tool for various branches of mathematical analysis and its applications. Polish mathematician Banach published his contraction Principle in1922. In 1928, Menger[17] introduced semi-metric space as a generalization of metric space. In 1976, Cicchese [6] introduced the notion of a contractive mapping in semi-metric space and proved the first fixed point theorem for this class of spaces. In 1986, Jungck [13] introduced the notion of compatible mappings. In 1997, Hicks and Rhoades[8] generalized Banach contraction principle in semi-metric space. In 1998, Jungck and Rhoades [14] introduced the notion of weakly compatible mappings and showed that compatible mappings are weakly compatible but not conversely. Recently in 2006,Jungck and Rhoades [15] introduced occasionally weakly compatible mappings which is more general among the commutativity concepts. Jungck and Rhoades[15] obtained several common fixed point theorems using the idea of occasionally weakly compatible mappings. Several interesting and elegant results have been obtained by various authors in this direction. There have been interesting generalized and formulated results in semi- metric space initiated by Frechet [7], Menger [17] and Wilson[20]. Also, in this paper, we prove a common fixed point theorem for three pairs of self-mappings using occasionally weakly compatible mappings.

### Fixed point theorems in fuzzy metric space via semi- compatible and occasionally weakly compatible mappings

Fuzzy set was defined by Zadeh [18]. Kramosil and Michalek [10] introduced fuzzy metric space, George and Veermani [7] modified the notion of fuzzy metric spaces with the help of continuous t-norms. Many researchers have obtained common fixed point theorem for mappings satisfying different types of commutativity conditions. Vasuki [17] proved fixed point theorems for R-weakly commuting mappings. Pant [12, 13, 14] introduced the new concept of reciprocally continuous mappings and established some common fixed point theorems. Balasubramaniam et al. [6] have shown that Rhoades [15] open problem on the existence of contractive definition which generates a fixed point but does not force the mappings to be continuous at the fixed point, posses an affirmative answer. Pant and Jha [14] obtained some anologous results proved by Balasubramanium et al.[6]. Recent literature on fixed point in fuzzy metric space can be viewed in [1, 2, 3, 4,5, 8, 11, 16].

### Common Fixed Point Theorem for Weakly Compatible Mappings in Metric Space

In 1976, Jungck proved some common fixed point theorems for commuting maps which generalize the Banach contraction principle. Further this result was generalized and extended in various ways by several authors. On the other hand Sessa [5] introduced the concept of weak commutativity and proved a common fixed point theorem for weakly commuting maps. In 1986, G.Jungck[1] introduced the concept of compatible maps which is more general than that of weakly commuting maps. Afterwards Jungck and Rhoades [4] introduced the notion of weakly compatible and proved that compatible maps are weakly compatible but not conversely.

### Common fixed point theorems for occasionally weakly compatible mappings in Menger spaces and applications

In 2008, Al-Thagafi and Shahzad [Generalized I-nonexpansive selfmaps and invariant approxima- tions, Acta Math. Sinica 24(5) (2008), 867–876] introduced the notion of occasionally weakly com- patible mappings (shortly owc maps) which is more general than all the commutativity concepts. In the present paper, we prove common fixed point theorems for families of owc maps in Menger spaces. As applications to our results, we obtain the corresponding fixed point theorems in fuzzy metric spaces. Our results improve and extend the results of Kohli and Vashistha [Common fixed point theorems in probabilistic metric spaces, Acta Math. Hungar. 115(1-2) (2007), 37-47], Vasuki [Common fixed points for R-weakly commuting maps in fuzzy metric spaces, Indian J. Pure Appl. Math. 30 (1999), 419–423], Chugh and Kumar [Common fixed point theorem in fuzzy metric spaces, Bull. Cal. Math. Soc. 94 (2002), 17–22] and Imdad and Ali [Some common fixed point theorems in fuzzy metric spaces, Math. Commun. 11(2) (2006), 153-163].

### Common Fixed Points of Occasionally Weakly Compatible in Intuitionistic Fuzzy Metric Space

Remark 1.2. The purpose of this paper is to prove some general common fixed point theorem for occasionally weakly compatible mappings satisfying implicit relations in intuitionistic fuzzy metric space which generalizes several results from the literature. Our results generalize several fixed point theorems in following respects.

### Hybrid contractions with implicit relations

Abstract. In this paper, we prove the existence of fixed points for two set-valued mappings and two single-valued mappings satisfying generalized contractive conditions by using the concept of weakly compatible mappings with control functions and implicit relations in complete metric spaces. Our results extend and generalize the corre- sponding result in Mehta and Joshi [21].

### Common fixed point theorem in fuzzy symmetric spaces

The above example reveals that occasionally weakly compatible mappings are not weakly com- patible. Since it has two coincidence points 1/2 and 1 (AP,S) and (BQ,T) are not commuting at x=1/2. We observed that the self mappings (A, P) and (B, Q) are commuting and the mappings A, B, S, T, P and Q have unique common fixed point.

### Common fixed point theorems for generalized contraction mappings in modular metric spaces

Abstract: The notion of modular metric spaces being a natural generalization of classical modulars over linear spaces Lebesgue, Orlicz, Musielak-Orlicz, Lorentz, Orlicz-Lorentz, and Calderon-Lozanovskii spaces was recently introduced. Chistyakov [4, 6] introduced and studied the concept of modular metric spaces and proved fixed point theorems for contractive map in Modular spaces. It is related to contracting rather “generalized average velocities” than metric distances, and the successive approximations of fixed points converge to the fixed points in a weaker sense as compared to metric convergence. In this paper, we prove some unique common fixed point theorems for generalized contraction type mappings for six self occasionally weakly compatible mappings in modular metric spaces.
