Also, we give a new generalization of the Mazur-Ulam theorem when X is a 2-fuzzy 2-normed linear space or (X) is a fuzzy 2-normed linear space, that is, the Mazur-Ulam theorem holds, when the 2-isometry mapped to a 2-fuzzy 2-normed linear space is attune.eninfo:eu-repo/semantics/closedAccessalpha-2-Norm2-Fuzzy 2-Normed linear spaces2-Isometry2-Lipschitz mappingArticle72109119Q1WOS:000279622200008Q1
