Coupled Fixed Points for Hardy-Rogers Type of Maps and Their Applications in the Investigations of Market Equilibrium in Duopoly Markets for Non-Differentiable, Nonlinear Response Functions
S. Kabaivanov, V. Zhelinski, B. Zlatanov
In this paper we generalize Hardy-Rogers maps in the context of coupled fixed points. We generalizes with the help of the obtained main theorem some known results about existence a…

Application of Coupled Fixed (or Best Proximity) Points in Market Equilibrium in Oligopoly Markets
Yulia Dzhabarova, Stanimir Kabaivanov, Margarita Ruseva +1
We present a possible kind of generalization of the notion of ordered pairs of cyclic maps and coupled fixed points and its application in modelling of equilibrium in oligopoly mar…
