Fractional chromatic numbers of cones over graphs
Claude Tardif · Journal of Graph Theory · 2001
Abstract We introduce a construction called the cone over a graph. It is a natural generalisation of Mycielski's construction. We give a formula for the fractional chromatic numbers of all cones over graphs, which generalizes that given in 3 for Mycielski's construction. © 2001 John Wiley & Sons, Inc.
