Abstract
The formal balls in fuzzy normed space 𝑋 (characterized by closed balls in 𝑋) are ordered by reverse inclusion depending on the concept of level sets. The set of formal balls in a fuzzy normed space is called a fuzzy domain normed space denoted by 𝐵𝑋. This set is directed complete partially ordered set (dcpo), its maximal elements are the suprema. A contraction mapping principle is defined on 𝐵𝑋. Banach fixed point theorem is studied and proved on 𝐵𝑋.
