Coupled fixed point theorems by altering distances between points in partially ordered metric spaces

Research Abstract
In this paper, some coupled coincidence and common xed point theorems for two self mappings have been derived which satisfy certain inequality involving a function of two variables that measures the distance between points in ordered metric spaces. For particular choices of the function several generalizations of many xed point theorems which contain altering distance functions may be obtained. Our results can be applied directly to study multidimensional xed point theorems which cover the concepts of coupled , tripled, quadruple xed point etc.

Common Fixed Point Theorems
For Four Weakly Compatible Mappings
In Menger Spaces

Research Abstract
In this paper, we show that some results of Sharma and Deshpande [19] are not valid, we also give supporting example. Finally, we consider the concept of weakly compatible mappings to improve the main result of Pathak [9].
