A Note on Various Types of Cones and Fixed Point Results in Cone Metric Spaces

Zoran Kadelburg, Stojan Radenovic


Various types of cones in topological vector spaces are discussed. In particular, the usage of (non)-solid and (non)-normal cones in fixed point results is presented. A recent result about normable cones is shown to be wrong. Finally, a Geraghty-type fixed point result in spaces with cones which are either solid or normal is obtained.
