Mutually nearest and farthest points of sets and the Drop Theorem in geodesic spaces
Espínola García, Rafael; Nicolae, Adriana (Springer, 2012-02)Let A and X be nonempty, bounded and closed subsets of a geodesic metric space (E, d). The minimization (resp. maximization) ...

New examples of subsets of c with the FPP and stability of the FPP in hyperconvex spaces
Espínola García, Rafael; Japón Pineda, María de los Ángeles; Souza, Daniel (Springer, 2021-07-22)The purpose of this work is two-fold. On the one side, we focus on the space of real convergent sequences c where we study ...
