| Abstract:
|
The inequality [math]\displaystyle{ \mu^{\frac{1}{\nu}} + \nu^{\frac{1}{\mu}} \leq 1/2 }[/math] is introduced and proved, where [math]\displaystyle{ \mu }[/math] and [math]\displaystyle{ \nu }[/math] are real numbers, for which [math]\displaystyle{ \mu, \nu \in [0, 1] }[/math] and [math]\displaystyle{ \mu + \nu \leq 1 }[/math]. The same inequality is valid for [math]\displaystyle{ \mu = \mu_A(x), \nu = \nu_A(x) }[/math], where [math]\displaystyle{ \mu_A }[/math] and [math]\displaystyle{ \nu_A }[/math] are the membership and the non-membership functions of an arbitrary intuitionistic fuzzy set [math]\displaystyle{ A }[/math] over a fixed universe [math]\displaystyle{ E }[/math] and [math]\displaystyle{ x \in E }[/math]. Also, a generalization of the above inequality for arbitrary [math]\displaystyle{ n \geq 2 }[/math] is proposed and proved.
