Abstract This short note is on the question whether intersection of all fixed points a positive arithmetic operator and its closed can proved to be equivalent in weak fragment second order arithmetic.

generalized geraghty type fuzzy mappings oncomplete metric spaces are introduced and a fixed point theorem thatgeneralizes some recent comparable results for fuzzy mappings incontemporary literature is obtained. example is provided to show thevalidity of obtained results over comparable classical results for fuzzymappings in fixed point theory. as an application, existence of coincidencefuzzy p...
