School of Physical Sciences ALGEBRA AND COMBINATORICS SEMINAR Tue 18 Mar 2008 3pm 67-641 Almost regular edge colourings and regular decompositions of complete graphs Darryn Bryant University of Queensland Abstract I will discuss a method for modifying any edge colouring of a complete graph so that the subgraph induced by each colour class is more regular. I will then show how the method can be used to give simple proofs of various results, some of which are known and some of which are new. All welcome.
