Asymptotic behavior of averaged and firmly nonexpansive mappings in geodesic spaces
(Elsevier, 2013-08)We further study averaged and firmly nonexpansive mappings in the setting of geodesic spaces with a main focus on the ...

Borsuk-Dugundji type extension theorems with Busemann convex target spaces
(Finnish Academy of Science and Letters, 2018)In this work we study continuity properties of convex combinations in Busemann convex geodesic spaces and apply them to obtain two extension results for continuous and Lipschitz mappings with values in a Busemann convex space.

Geodesic Ptolemy spaces and fixed points
(Elsevier, 2011-01-01)We prove that geodesic Ptolemy spaces with a continuous midpoint map are strictly convex. Moreover, we show that geodesic ...

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