A quantum chemical investigation was carried out to study the properties of intermolecular F•••F, Br•••Br and Br•••O interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (BFNB). This system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. We found that fluorine atoms have weak ...

In this paper, we investigate the relationship between weak min-max property and diameter uniformity of domains in Banach spaces with dimension at least 2. As an application, show that uniform are invariant under relatively quasimöbius mappings.
