  • Some behavior of coarse structure and coarse equivalent 
    Kajan, N.; Kannan, K. (Union of researchers of Macedonia, 2022-09-05)
    I am going to introduce some properties of coarse structure. Coarse space is defined for large scale in metric space similar to the tools provided by topology for analyzing behavior at small distance, as topological property ...
  • Some Results on Fuzzy metric space and some examples of fuzzy b-metric space 
    Kajan, N.; Kannan, K. (Union of researchers of Macedonia, 2020-08-24)
