Doctor Darcy

June 23rd, 2018 by iwanless

Great work by Darcy Best, whose PhD was officially ratified by the powers-that-be on June 20. So he is now a dinky-di doctor of philosophy. If you have any philosophical ailments, book an appointment. I’m sure his fees are reasonable.

Darcy’s thesis was entitled “Transversal This, Transversal That”. It is available here:

Congratulations Darcy Best

Monash PhD student Harald Bögeholz won the inaugural Anne Penfold Street Student Prize, for the best student talk at the conference 5ICC.

Harald’s presentation was entitled “Calculating Connected Components in Huge Graphs by Randomised Contraction”. Warm congratulations to Harald.


5th International Combinatorics Conference a big success

December 9th, 2017 by iwanless

Monash hosted the 5th International Combinatorics Conference from 3-9 December 2017. It was attended by 163 mathematicians and students from Australia, Canada, China, Croatia, Czechia, Germany, Hungary, India, Indonesia, Iran, Israel, Japan, Malta, New Zealand, Singapore, Slovenia, South Africa, South Korea, Sri Lanka, Switzerland, Thailand, United Kingdom, United States and Vietnam (fully justifying the name of the conference!). There were 124 talks, 2 excursions, a public lecture and a memorable dinner.

Bill Tutte Centenary Celebration

September 25th, 2017 by David Wood

Today we celebrated the Bill Tutte Centenary Year with a half-day event consisting of the following short talks about his life, work, and influence on mathematics:

Graham Farr: Overview of Tutte’s life
Kerri Morgan: Squaring the square
Ron Steinfeld / Amin Sakzad: Tutte’s work at Bletchley Park in WW2
Kai Siong Yow: The dissection of equilateral triangles into equilateral triangles
Graham Farr: A ring in graph theory
Ranjie Mo: A contribution to the theory of chromatic polynomials
Jane Gao: When can vertices be all paired up?
Sanming Zhou (Melb): A family of cubical graphs
David Wood: How Tutte would draw a graph
Grant Cairns (La Trobe): The Hanani-Tutte Theorem
Norman Do: Tutte’s topological recursion
Daniel Mathews: The Tutte polynomial and knot theory
Andrew Elvey Price (Melb): Some counting problems on planar maps
Nick Wormald: My impressions of Tutte

William (Bill) Tutte (1917-2002) became a research mathematician while still an undergraduate at Cambridge in the late 1930s, broke the toughest Nazi codes while at Bletchley Park in WW2, and became one of the greatest mathematicians of the 20th century. His work saved countless lives during the war and led the development of graph theory. His work was usually inspired by pure curiosity or recreational puzzles, but has been applied in domains as diverse as electrical circuits, statistical physics and information visualisation.

Nick Wormald FAA

May 22nd, 2017 by David Wood

Nick Wormald is one of the 21 new fellows elected to the Australian Academy of Science. Congratulations Nick!

The citation: Nicholas Wormald is one of an elite group of mathematicians globally who combine the most advanced probability theory, combinatorics and theoretical computer science to produce deep insights into the nature of random and complex networks. He specialises in random graphs and probabilistic combinatorics, graph theory, enumeration, the analysis of graph algorithms, Steiner trees, the analysis of real-life networks, and other areas in combinatorics, as well as the optimisation of underground mine access networks. Wormald is responsible for an impressive number of major breakthroughs in these areas and many standard methods used today were his invention.
