Isolated vertices and diameter of the $B J$ -orthograph in $C^{*}$ -algebras

Dragoljub J. Kečkić, Srdjan Stefanović

We give necessary and sufficient condition that an element of an arbitrary $C^{*}$ -algebra is an isolated vertex of the orthograph related to the mutual strong Birkhoff-James ortho…

TVS-cone metric spaces as a special case of metric spaces

Ivan D. Aranđelović, Dragoljub J. Kečkić

There have been a number of generalizations of fixed point results to the so called TVS-cone metric spaces, based on a distance function that takes values in some cone with nonempt…
