The upper chromatic number of quasi-interval co-hypergraphs

open access: yesLe Matematiche, 1997
We investigate the structural and colouring properties of clique hyper-graphs of interval graphs called the quasi-interval hypergraphs. We find the conditions when they are interval hypergraphs. The upper chromatic number for the clique co-hypergraphs of

The circular chromatic number of hypergraphs

open access: yes, 2005
A generalization of the circular chromatic number to hypergraphs is devel-oped. Circular colourings of graphs and hypergraphs are first discussed and it is shown that the circular chromatic number of a graph is the same regard-less of whether the ...
