Perov studied the Banach contraction principle in framework of a generalized metric space and presented condition where contractive constant is replaced by matrix with nonnegative entries spectral radius less than 1. Azam et al. notion rectangular cone following idea Branciari, Huang Zhang replacing triangular inequality inequality. Motivated work Abbas Vetro Radenovi´c, purpose this paper to i...
and Applied Analysis 3 Let X, d be an abstract metric space. The following properties are often used, particularly in the case when the underlying cone is nonnormal. The only assumption is that the cone K is solid. For details about these properties see, for example, 11 . p1 If a ha where a ∈ K and h ∈ 0, 1 , then a θ. p2 If θ u c for each c, θ c, then u θ. p3 If u v and v w, then u w. p4 If c ...
recently, rahimi et al. [comp. appl. math. 2013, in press] de ned the conceptof quadrupled xed point in k-metric spaces and proved several quadrupled xed pointtheorems for solid cones on k-metric spaces. in this paper some quadrupled xed point resultsfor t-contraction on k-metric spaces without normality condition are proved. obtainedresults extend and generalize well-known comparable result...
In this paper, we prove a general fixed point theorem in $textrm{S}$-metric spaces for maps satisfying an implicit relation on complete metric spaces. As applications, we get many analogues of fixed point theorems in metric spaces for $textrm{S}$-metric spaces.
