... metric space then X is an ultrametric space. Ultrametric spaces arise in the study of non-Archimedean analysis, and in particular in the study of Banach space over non-Archimedean valuation fields ... Tx  d A, B. In 2009, Al-Thagafi and Shahzad introduced a new class of mappings, namely, the class of cyclic ϕ-contraction maps. This new class contains the class of cycl...
