Darryn Bryant and Daniel Horsley of the University of Queensland have solved a conjecture, first posed by Curt Lindner of Auburn University 30 years ago. More information on this can be obtained from:

UQ student solves a 30 year old mathematics problem - UQ News and Two-Up in Solution Breakthroughs.

Rod Downey of Victoria University of Wellington (NZ) will deliver a 45-minute invited lecture at the International Congress of Mathematicians (ICM), to be held in Madrid (Spain) during August 22-30, 2006. Rod is the first New Zealand based mathematician to be awarded this honour. Rod's lecture on Algorithmic Randomness and Computability will be in the Logic and Foundations section of the ICM.

In addition, Rod will be giving an invited hour-long plenary address at the next International Congress of Logic, Philosophy and Methodology of Science at Beijing in 2007 (The logic and philosophy version of the ICM), as well as a tutorial consisting of 3 lectures at the next (2006) Logic Colloquium in Europe.
