* AIMS of the newsletter * CMSA SECRETARY AND TREASURER * RECENT CONFERENCE REPORTS * FUTURE WORKSHOP AND CONFERENCE ANNOUNCEMENTS * RECENT NEWS OF CMSA MEMBERS * MEMBERS (OR STUDENTS OF MEMBERS) RECENT RESEARCH DEGREES * AUSTRALASIAN JOURNAL OF COMBINATORICS
AIMS of the newsletter:
* to promote combinatorics within Australasia * to provide a forum for sharing combinatorial and related information * to keep CMSA Members informed and in touch with combinatorial and related matters
CMSA SECRETARY AND TREASURER:
After making a great contribution to the CMSA over a period of years, Helen Gustafson and Ed Dawson are planning on retiring from the date of the AGM at the Perth ACCMCC in July next year. We are therefore seeking people who might be interested in being nominated for these positions. Because the CMSA is incorporated in Queensland, it appears necessary for the secretary to come from that State.
These positions involve a non-trivial amount of work. We are advertising them well in advance so that potential nominees will have time to think carefully about the positions well before the Perth AGM.
Anyone interested in the posts might like to get in touch with Helen at h.gustafson@fsc.qut.edu.au or Ed at dawson@fit.qut.edu.au regarding the magnitude and scope of the jobs. If not already on Council, potential secretaries and treasurers might like to be nominated for Council to gain some experience of the way that it works before taking on an executive role.
Derek Holton CMSA President
RECENT CONFERENCE REPORTS:
The 44th Annual Meeting of the Australian Mathematical Society, held at the University of Queensland in early July 2000, included a Special Session on Combinatorics. Besides a plenary talk from Peter CAMERON entitled The random graph revisited, (see http://www.maths.qmw.ac.uk/~pjc/slides/ from Peter's home page, for slides), there were 13 shorter talks presented. The speakers were
Lynn Batten Simon Blackburn Andrew Blinco N.J. Cavenagh Michelle Davidson Roger Eggleton Joanne Fuller Yvonne Hitchcock Kathy Horadam Andrei Kelarev Wei-Hung Liu E.S. Mahmoodian Ian Roberts
The Eleventh Australasian Workshop on Combinatorial Algorithms was held from 29th July to 1st August at the Pokolbin Village Resort in the Hunter Valley and organised by the University of Newcastle's Department of Computer Science and the School of Management.
The resort is in the middle of Pokolbin's vineyards, within walking distance of several wineries and driving distance of many more. The accommodation was excellent with helpful staff who remained calm even when it was found, two hours before commencement, that the overhead projector wasn't working. Four computer scientists, each giving contradictory advice, were able to get it going again in time for the opening address by Professor Janet Aisbett, Head of the School of IT.
AWOCA is held annually and is intended to be a small gathering of combinatorial algorithmic specialists sharing their ideas and problems. This year there were 38 delegates from 11 countries.
Invited speakers were Martin Baca (Slovakia), Brendan McKay (ANU), Frank Ruskey (Canada), Jennifer Seberry (Wollongong) and Nick Wormald (Melbourne).
Although many types of algorithm were considered there were also many talks on graph labelling, particularly magic and antimagic labellings. A special feature was the Sunday Symmetry Day with talks on graph drawing and associated topics.
There was also a problem session organised by Sue Whitesides. Sue is writing up the problems and they will soon appear on the workshop's web site http://www.cs.newcastle.edu.au/~awoca2000/ .
The main workshop dinner was held at the nearby Rothbury Estate in a spectacular setting. We were placed along a long table in a barn-like building with two levels of giant barrels lining each side. Impromptu entertainment was provided by a capella performance by Jennie Seberry and Elias Dahlhaus singing, respectively, in English and German.
The Twelfth AWOCA will be held in July 2001 at ITB Bandung, Indonesia.

Emerging Applications of Combinatorial Designs
Sunday, November 5, 2000 through Friday, November 10, 2000
Organizing Committee: Esther Lamken (chair), Charlie Colbourn, Jeff Dinitz
This workshop will emphasize constructions and computational methods for combinatorial designs and the growing number of new and useful applications of designs in biology/biotechnology, computer science, information theory, and numerical finance. All of these applications share a common feature; they require the construction of highly structured combinatorial designs. In recent years a great deal of work has been done on developing new constructions for designs and a powerful theory of combinatorial constructions is emerging. So these new applications come at a time when the power of combinatorial constructions combined with computational methods is beginning to be fully realized. The problems appearing in these applications are providing us with new and challenging existence questions as well as surprising applications of familiar and long studied combinatorial designs. The purpose of this workshop is to bring together experts in the construction and analysis of designs and researchers from industry and other departments who have come up with problems in design theory.
The workshop will feature keynote talks on applications of designs in biology/biotechnology, computer science, information theory, and numerical finance as well as talks in the areas of design theory that come up frequently in applications including computational methods, combinatorial constructions, and coverings and packings.

RECENT NEWS OF CMSA MEMBERS:
MARGARET MORTON
With much sadness we have to report the death of our friend and colleague, Margaret Morton, aged only 56. As some of you will know already, Margaret discovered late last year while on leave in the US that she had stomach cancer. Margaret underwent a course of chemotherapy before returning to Auckland in April, but the cancer was widespread by that stage, and her health deteriorated quite quickly. She was admitted to a hospice mid-August, and with her children (Dave, Robyn and Andy) and her brother (Don James) present, she died peacefully on 31st August.
Margaret was an amazing person. After years of raising a family and then moving back home to New Zealand from the US in the mid-1980s, she set out to establish an academic career at the University of Auckland while in her 40s. This was no mean feat! In addition to teaching and more general service, Margaret wanted to fully engage in research, in both pure mathematics and mathematics education. The fact that she succeeded in all these areas is a tribute to Margaret's tenacity and inner strength, as well as her natural ability.
Following an early publication in 1976, Margaret returned to research in the late 1980s and went on to publish 8 papers in graph theory between 1990 and 1999, six of these in the last five years, and many more in maths education. Initially she worked with Marston Conder and Cheryl Praeger, but also she did some great work on her own, established a joint programme with Neal Brand in Texas, and combined with Paul Bonnington to win a Marsden Fund grant in 1998.
Although Margaret was always modest of her abilities and the results of her research, what she achieved was phenomenal. Also, at Auckland she made us all sit up and re-think what we do in the Department. She helped us learn to see things from many perspectives (not just our own), and was a wonderful advocate for students and for younger staff. She did a fantastic job as Teaching Coordinator, helping introduce much better feedback mechanisms and well thought out processes for maintaining and improving our teaching resources.
She was also a champion for new appointments, and especially the need for mentoring of new and younger staff.
Margaret was devoted to her family, and had a wide range of personal interests, especially outdoor activities such as tennis, walking, kayaking and golf. She particularly loved the ocean.
We have decided to dedicate our conference in Auckland in mid-December (on Algebraic and Topological Methods in Graph Theory) to Margaret, and we are planning a half-day special session in her honour. Further details about the conference can be found at http://www.scitec.auckland.ac.nz/atmgt2000/ .

NICHOLAS and Jillian HAMILTON are now the proud parents of a 3.9 kg baby boy, called Edan Jack Hamilton. Nick says Edan is a celtic name which means "little fiery one". Congratulations to both Jillian and Nick; the sleepless nights will be worth it! Nick says:
"At about 11 pm on Monday the 25th of September (that makes him a libran) Jillian popped the sprog. Both are doing really well. He weighed 8 pounds 9 ounces (3.9 Kg) so is quite a big boy! He's a handsome devil as well. The labour took about 6 hours, and Jillian was brilliant. I thought they were supposed to swear at the husband. The only time she swore was when she said "Where's that **** anesthetist?". The whole birth was truly amazing. Seeing the head pop out was unbelievable."
He also has pictures on the web; see

Jillian, Nick and Edan will return from Brisbane to Gent around 8 October.
Further CONGRATULATIONS to NICHOLAS HAMILTON: The Institute of Combinatorics and its Applications awarded Nicholas a Kirkman Medal in 1999; this was presented to him at the Isle of Thorns Conference (U.K.), which was held from 16-21 July 2000.
The Australian Mathematical Society Medal for 2000 was shared by two people, one of whom is CHRISTINE O'KEEFE. This medal is the Australian Mathematical Society's most prestigious award; it is awarded to a member of the Society, under 40 years of age on 1 Jan 2000, for distinguished research in the Mathematical Sciences. This was presented at the 44th Annual Meeting of the AustMS, held at the University of Queensland in July 2000. Congratulations to Christine!
CHRISTINE O'KEEFE joined the Business Intelligence group in CSIRO Mathematical and Information Sciences in April 2000, taking leave without pay from her Queen Elizabeth II Fellowship at the University of Adelaide. The position at CSIRO was originally for six months, but on 1 September 2000 Christine accepted an indefinite appointment. Christine writes "I will certainly miss the Australian and international combinatorics and geometry communities and activities ... especially the many friends I have made all over the world. I would like to thank everyone for their friendship, help and support throughout my career (so far!), and I trust that we'll stay in touch in the future. However I am enjoying the new challenges presented by my position at CSIRO, including whole new fields of mathematics."
Christine also included information about vacation scholarships at CSIRO, although the official closing date for these has just passed. Nevertheless, here is the information she sent:
I'd like to encourage people to encourage their good students to apply for vacation scholarships at CSIRO. Students are treated very well and should gain a lot from the experience. Check www.cmis.csiro.au/Positions.Vacant and follow the links under Undergraduate Vacation Scholarship Program.
The scholarships are intended to provide students with the opportunity to work on a real world problem and to develop future links with the Division. Undertaking a CMIS project has influenced previous scholarship holders in their choice of further study and future career. Many have gone on to undertake PhDs in the Division and to be employed in senior positions in CSIRO, Universities and industry.
The scholarships are open to students who have completed at least three years of undergraduate study and should have maintained a credit average or better. The scholarship rate is $525 per week, placements are from late November to February for a period of 8 - 12 weeks.
There are some really interesting projects including: Artificial Intelligence in e-Business Internet Marketplaces Business Intelligence Business and Financial Engineering and many others.
In some email from CURT LINDNER in Auburn:
Subject: How to be an administrator
Lesson 1. Pair a word from the left list with a word from the right list. Select the words at random. When you have, say, five distinct pairs, write a one-page memorandum using these pairs once each. Repeat using more and more pairs. The more pairs you use, the longer your memo can be. To get an A+, you need to use all 196 possible pairs in a single memo.
achieving vision
creating gap
strategic initiatives
tactical actions
define projects
justify survey
implementation strategy
phase completion
fund objective
manage mission
successful goals
position phases
support expertise
information technology
Lesson 2. Choose at random two words from the left list and put either and or or between them. Do the same from the right list to form a pair. Repeat Lesson 1 with pairs formed in this way.
Lesson 3. Put Boolean connectives between three---or even more, for a real fun time---words from each list and proceed as before. The least comprehensive memo resulting in this manner will earn the author a doctoral degree in administration.
OK; I know this has been done before. However, the words in the above lists all appear in a recent IT memo from the president.
MEMBERS (OR STUDENTS OF MEMBERS) RECENT RESEARCH DEGREES :
The Engineering, Physical Sciences and Architecture Faculty, EPSA, at the University of Queensland, has a Dean's Commendation List for Outstanding PhD theses (generally the top 10%). These have recently been decided for students obtaining their PhD in 1999. Four of these were in combinatorics [supervisors given in brackets]:
* Phil HAWKES [D. Donovan/L. O'Connor]; * Barbara MAENHAUT [A. Street/M. Sharry]; * Sarah ZAHRAI [S. Williams/B. Jones]; * Marks NESTER [A. Street/K. Matthews].
Congratulations to these four people for their highly successful PhD theses!
