Isolated vertices and diameter of the -orthograph in -algebras
Dragoljub J. Kečkić, Srdjan Stefanović
We give necessary and sufficient condition that an element of an arbitrary -algebra is an isolated vertex of the orthograph related to the mutual strong Birkhoff-James ortho…
Operator versions of Hölder inequality and Hilbert -modules
Dragoljub J. Kečkić
Recently proved weighted Cauchy Scwarz inequality for Hilbert -modules leads to many Hölder type inequalities for unitarily invariant norms on Hilbert space operators.
On the continuity of probabilistic distance
Dragoljub J. Kečkić, Marina Milovanović-Aranđelović
The famous result of B.~Schweizer and A.~Sklar [Pacific J Math 10(1960) 313--334 - Theorem 8.2] asserts that, given a probabilistic metric space , $\mathcal F=\{F…
Continuous generalization of Clarkson-McCarthy inequalities
Dragoljub J. Kečkić
Let be a compact abelian group, let be the corresponding Haar measure, and let be the Pontryagin dual of . Further, let denote the Schatten class of opera…
The index of a subspatial product system over a Hilbert -module -- an example
Dragoljub J. Kečkić, Biljana Vujošević
Recently, Bhat, Liebscher and Skeide exhibited an unusual example of product system of Hilbert modules. Namely, a subsystem of a Fock system, that is not Fock. Later, the aut…
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…
