Remarks on “Perov Fixed-Point Results on F-Contraction Mappings Equipped with Binary Relation”

Since 1964, when I.A. Perov introduced the so-called generalized metric space where d(x,y) is an element of vector Rm, many researchers have considered various contractive conditions in this type space. In paper, we generalize, extend and unify some those established results. We are primarily concerned with examining existence a fixed point mapping from X to itself, but if (x,y) belongs relation R on set X, then binary F contraction defined cone Rm combined. start our consideration recently announced results give them strict, critical remarks. addition, improve several by weakening given conditions.
