Banach Spaces Generated by Finite-Valued Functions: Superreflexive Rigidity, Hankel Operators, and Universality
Miroslav Hristov, Atanas Ilchev, Diana Nedelcheva +1
We investigate Banach spaces generated by uniformly bounded families of functions taking values in a fixed finite set and establish a rigidity principle connecting the cardinality…
Perturbation Method in Musielak-Orlicz Sequence Spaces
Pando Georgiev, Vasil Zhelinski, Boyan Zlatanov
We generalize an abstract variational principle in Banach spaces, introduced by Topalova \& Zlateva, by showing that the set of perturbations for which a perturbed l…
Equilibrium in the Canonical Stackelberg Triopoly via Response Functions and Fixed Point Theory
Anton Badev, Martin Pavlov, Boyan Zlatanov
We analyze a canonical extension of the Stackelberg duopoly to a sequential framework, where each firm strategically anticipates the reactions of all subsequent players. In a triop…
On the UC and UC* properties and the existence of best proximity points in metric spaces
Vasil Zhelinski, Boyan Zlatanov
We investigate the connections between UC and UC* properties for ordered pairs of subsets (A,B) in metric spaces, which are involved in the study of existence and uniqueness of bes…
Error Estimates for Approximating Best Proximity Points for Cyclic Contractive Maps
Boyan Zlatanov
We find a priori and a posteriori error estimates of the best proximity point for the Picard iteration associated to a cyclic contraction map, which is defined on a uniformly conve…
Fixed Points for Mappings with a Contractive Iterate at Each Point
Samet Karaibryamov, Boyan Zlatanov
We generalize the results of Sehgal and Guseman for mappings on a complete metric space with a contractive iterate condition at each point.
