NEWS from the CMSA PRESIDENT

This year is quite a busy one for the combinatorics conferencer. For instance, in Melbourne we will have two international conferences in July, the first on Stochastic Processes and their applications (the scope includes discrete random processes) which will be immediately followed by FPSAC. Simultaneous with the Stochastic Processes is ACISP, on Information Security, also in Melbourne, and simultaneous with FPSAC is the AWOCA meeting at Fraser Island. These conferences and more are mentioned in the conference section of this newsletter.

Professor Brendan McKay deserves congratulations for obtaining one of the 23 ARC Professorial Fellowships awarded in 2002. Probably not all members are aware that this is the first year of a new scheme, a little different from the earlier "Senior Research Fellows".

Sadly, Professor Bill Tutte passed away earlier this month. His eminence in the field, including his achievements in code-breaking of the Lorenz cipher in World War II, would be hard to surpass. His interest in combinatorics and in continued contact with his combinatorial colleagues remained with him until the end. I heard that it was for this reason that he moved back, a year or two ago, to Waterloo from the UK. Only last October, he became an Officer of the Order of Canada. An obituary is at http://www.cms.math.ca/bulletins/obit.html and there are a few nice web pages on the Lorenz cipher at http://www.codesandciphers.org.uk/lorenz/fish.htm.

It is regrettable that Professor Herb Shank also passed away recently. Herb worked on graph theory, embeddings and polynomials. Herb spent a good deal of time at Waterloo, though probably not as much as Bill Tutte. Anne Street pointed out to me that both Bill and Herb were invited speakers at the first combinatorics conference in Brisbane (the third Australian conference, in 1974). Bill talked about the graph of the chromatic polynomial of a graph, and Herb talked about left-right paths in a plane graph. Anne also recalls that Bill's presence was assisted by an eclipse of the sun, not visible from the Northern Hemisphere, making it possible to snare him as he went by to observe it.

EWM International Workshop on Groups and Graphs The EWM (European Women in Mathematics) organises general meetings each odd year and specialised workshops each even year. Their aim is to bring together young researchers and women-experts in some fields of mathematics, give them the opportunity to present their results, and the methods and techniques they use, and thus encourage young women to remain in Mathematics.

All the invited speakers will be women, but otherwise the workshop is open to everybody who works, or has any interest in, GROUPS and GRAPHS.

The Workshop will be held in Bulgaria on the coast of the Black Sea from August 31 to September 6, 2002. Early registration closes 30 June 2002. For further information please see the web page at http://www.moi.math.bas.bg/EWM02/

The XVIth Midwestern CCCC The XVIth Midwestern Conference on Combinatorics, Computing and Cryptography will take place at Southern Illinois University, Carbondale, starting at 9 am on Thursday November 7th and concluding in mid-afternoon of Saturday November 9th.

A list of invited speakers and further conference details will be announced late in July.

Contributed talks are welcome in any area of combinatorial mathematica or combinatorial computing. Talks will be of 20 minutes duration, including discussion time.

The 27th ACCMCC The 27th Australasian Conference on Combinatorial Mathematics and Combinatorial Computing (27ACCMCC) will be held at Newcastle University, NSW, from 9-13 DECEMBER 2002. The invited speakers are:

New Zealand MRI Summer Workshop

This year the annual NZMRI summer workshop will be based in beautiful New Plymouth in the North Island of New Zealand. This follows previous workshops in Huia (1994), Tolaga Bay (1996, 1997), Napier (1998, 2002), Raglan (1999), Kaikoura (2000), and Nelson (2001).

The topic for New Plymouth (2003), will be Combinatorics and Combinatorial Aspects of Biology although this will be interpreted broadly. As usual, families are invited to come. We especially encourage New Zealand graduate and senior students, and ask that most of the talks be directed at a graduate student level. The standard format is that we have lectures in the morning, the afternoons are left free for individual pursuits, families, sightseeing, mathematical discussions, and the like, and we have lectures in the early evening after dinner. There will also be one day off (traditionally Wednesday).

We have a stellar group of speakers, all of whom are world renowned mathematicians and computer scientists, and very fine speakers. We have asked that the speakers give a series of 2-3 lectures for this workshop, the first two being easily accessibly to graduate students.

Our speakers currently include (in no particular order):

* Karl Broman (Johns Hopkins University, Recombination Mapping) * Mike Hallett (Magill University, Parametric Aspects of Computational Biology) * Neil Robertson (Ohio State University, The Graph Minors Project) * Martin Grohe (University of Edinburgh, Logical Aspects of Graphs) * Andreas Dress (University of Bielefeld, Overview of Combinatorial Biology) * Tandy Warnow (University of Texas, Mathematical Aspects of Phylogeny) * Lior Pachter (University of California, Berkeley, Genefinding) * Terry Speed (University of California, Berkeley, Mathematical Aspects of Gene Expression) * Richard Stanley (MIT, Enumerative Combinatorics).

It is primarily being organized by Geoff Whittle Geoff.Whittle@mcs.vuw.ac.nz and Rod Downey rod.downey@vuw.ac.nz of Victoria University, who will be happy to answer any questions.

This should be a wonderful workshop. As usual, we will cover most local costs for NZ residents. This year we will make sure that the meeting does not get too big. We will soon be putting out an announcement asking for numbers. If you wish to be on such a list, please e-mail Geoff Whittle: Geoff.Whittle@mcs.vuw.ac.nz.

Permutation Patterns - 2003

Permutation Patterns - 2003 will be held at the University of Otago, New Zealand, 10 - 14 February 2003.

See  http://www.cs.otago.ac.nz/staffpriv/mike/PP2003/FirstAnnouncement.html   for more information.

Graph Theory of Brian Alspach

Brian Alspach is 65 next year and we are celebrating his birthday in a spectacular "Graph Theory of Brian Alspach" conference from May 25 to 29 of 2003 on the beautiful campus of Simon Fraser University.
