“…It asserts that every contraction mapping on a complete metric space possesses a unique …xed point. Several extensions of this principle were considered by many authors to various generalized contractions and di¤erent type of spaces (see [1], [3], [4], [5], [6], [8], [10], [12], [18], [20], [21], [26]). Wardowski [26] generalized the Banach contraction principle by introducing the notion of F-contraction on metric spaces.…”
