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…

The index of a subspatial product system over a Hilbert $C^{*}$ -module -- an example

Dragoljub J. Kečkić, Biljana Vujošević

Recently, Bhat, Liebscher and Skeide exhibited an unusual example of product system of Hilbert $C^{*}$ modules. Namely, a subsystem of a Fock system, that is not Fock. Later, the aut…
