Abstract
Pete Johnson (Auburn University), Hall t-chromatic graphs
Abstract:
The property of being Hall t-chromatic was discovered during
investigations concerning list-coloring of graphs,
and is not difficult, but is a little too abstruse to be expressed in
an abstract. The incentives for looking into it are that it provides an
indirect attack on a certain extremal problem involving the fractional
chromatic number, and it raises a number of attractive questions that
are still open.
