On the Intuitionistic fuzzy topological (metric and normed) spaces
In this paper, we define precompact set in intuitionistic fuzzy metric spaces
and prove that any subset of an intuitionistic fuzzy metric space is compact if
and only if it is precompact and complete. Also we define topologically
complete intuitionistic fuzzy metrizable spaces and prove that any set in a complete intuitionistic fuzzy metric spaces is a topologically
complete intuitionistic fuzzy metrizable space and vice versa. Finally, we
define intuitionistic fuzzy normed spaces and fuzzy boundedness for linear
operators and so we prove that every finite dimensional intuitionistic fuzzy
normed space is complete.Comment: 16 page
Integrated and Differentiated Spaces of Triangular Fuzzy Numbers
Fuzzy sets are the cornerstone of a non-additive uncertainty theory, namely
possibility theory, and of a versatile tool for both linguistic and numerical
modeling. Numerous works now combine fuzzy concepts with other scientific
disciplines as well as modern technologies. In mathematics, fuzzy sets have
triggered new research topics in connection with category theory, topology,
algebra, analysis. In this paper, we use the triangular fuzzy numbers for
matrix domains of sequence spaces with infinite matrices. We construct the new
space with triangular fuzzy numbers and investigate to structural, topological
and algebraic properties of these spaces.Comment: 10 pages, 17 reference
