On a Class of Ky Fan-Type Inequalities [PDF]

International Journal of Mathematics and Mathematical Sciences, 2009
We study one class of Ky Fan-type inequalities, which has ties with the original Ky Fan inequality. Our result extends the known ones.

Operator Ky Fan type inequalities [PDF]

Linear Algebra and its Applications, 2018
In this paper, we extend some significant Ky Fan type inequalities in a large setting to operators on Hilbert spaces and derive their equality conditions.

Weighted entropy: basic inequalities

Modern Stochastics: Theory and Applications, 2017
This paper represents an extended version of an earlier note [10]. The concept of weighted entropy takes into account values of different outcomes, i.e., makes entropy context-dependent, through the weight function.

On the Ky Fan inequality

Journal of Mathematical Analysis and Applications, 2002
The Ky Fan inequality asserts that \[ \left[ \prod_{i=1}^{n}x_{i}\biggl/\prod_{i=1}^{n}(1-x_{i})\right]

Fuzzy Strong Nash Equilibria in Generalized Fuzzy Games with Application in Urban Public-Sports Services

Mathematics, 2022
In this paper, we apply the existence of solutions of the Ky Fan minimax inequality to establish the existence of fuzzy strong Nash equilibria in generalized fuzzy games and strong Nash equilibria in fuzzy coalition generalized games.

On the Ky Fan inequality and related inequalities I [PDF]

Mathematical Inequalities & Applications, 2002
Ky Fan type inequalities for means of two or more variables are obtained. Refinements and improvements of known inequalities are derived. Applications to symmetric elliptic integrals of the first and second kind are also included.

On Ky Fan's inequality [PDF]

Mathematical Inequalities & Applications, 2001
The authors prove the Ky-Fan like inequalities \({\mathfrak H_n( \underline a; \underline w)\over\mathfrak H_n' ( \underline a; \underline w)}\leq {\mathfrak G_n( \underline a; \underline w)\over\mathfrak G_n' ( \underline a; \underline w)}\), where the notation \(\mathfrak H_n' ( \underline a; \underline w)\) for \(\mathfrak H_n' ( 1-\underline a ...

Generalizations of the Nash Equilibrium Theorem in the KKM Theory

Fixed Point Theory and Applications, 2010
The partial KKM principle for an abstract convex space is an abstract form of the classical KKM theorem. In this paper, we derive generalized forms of the Ky Fan minimax inequality, the von Neumann-Sion minimax theorem, the von Neumann-Fan intersection ...
