Fuzzified group actions

  • Ju-Mok OhEmail author


Recently, the concept of fuzzy actions, a fuzzified concept of group actions, has been introduced to deal with situations where imprecision and uncertainty are present. In this paper, we redefine the concept of fuzzy actions in a rather simple form to be more suitable for ambiguous situations. We demonstrate that this redefined concept is consistent with the well-known concept of quasi-perfect fuzzy actions and derive various mathematical properties of fuzzy actions related with the concept of fuzzy functions.
