STUDENT PRIZE

The Student Prize for the best student talk at the annual CMSA conference was awarded for the first time at the 26th ACCMCC at Curtin University in July this year. The panel of three were impressed with the quality of all the student talks, and finally awarded the prize of $300 (Australian) to Dillon Mayhew from Victoria University of Wellington for his talk entitled "Inequivalent representations of matroids having no U3,6 minor".

The aims of the prize are

  1. to foster student interest and involvement in the ACCMCC conferences, and
  2. to encourage good presentation of student talks.

For more details please contact the President of the CMSA, Professor Nick Wormald, at nick@ms.unimelb.edu.au.


RECENT CONFERENCE REPORTS: REPORT ON THE 26th ACCMCC at Curtin University of Technology, 9-13 July 2001.

The 26th Australasia Conference on Combinatorial Mathematics and Combinatorial Computing (26th ACCMCC) was held at Curtin University of Technology, Perth, Western Australia, from 9-13 July 2001. We had a total of 52 registered participants, plus a number of students.

We gratefully acknowledge the generous sponsorship given by:

   * Department of Mathematics and Statistics, Curtin University of Technology
   * Division of Engineering and Science, Curtin University of Technology
   * The Western Australian Centre of Excellence in Industrial Optimisation (WACEIO)
   * Australian Telecommunications Research Institute (ATRI), Curtin University of Technology
   * The Institute of Combinatorics and its Applications (ICA)
   * Department of Mathematics and Statistics, The University of Western Australia

The conference's Invited Speakers were:

   * Richard Anstee (University of British Columbia, Canada)
   * Elizabeth Billington (University of Queensland, Australia)
   * Curt Lindner (Auburn University, USA)
   * John Moon (University of Alberta, Canada)
   * Cheryl Praeger (University of Western Australia)
   * Wal Wallis (Southern Illinois University, USA)

The excellent presentations from the invited speakers were well supported by 34 contributed talks covering a wide range of topics in the area of combinatorial mathematics, combinatorial computing and combinatorial optimisation.

Prior to the conference the CMSA Council decided to award a Student Prize ($300 Australian) for the best student talk at the conference. The prize committee was given the challenge of awarding this prize from the many eligible candidates. The inaugural prize was awarded to Dillon Mayhew from Victoria University of Wellington, New Zealand.

The social program included:

   * An informal pre-conference reception at Curtin University on the Sunday evening.
   * A full day excursion on Wednesday. The excursion was a bus trip through Perth, Fremantle and the Swan Valley Wineries. We lunched at Fremantle's Fisherman's Harbour and tried some serious wine tasting at the Houghton's and Sandalford Wineries. The day ended with coffee and cake of the day at Sandalfords.
   * The conference dinner was held on Thursday at The Boatshed Restaurant, located on the banks of the Swan River. In addition to fine food and local wines, delegates were able to enjoy the magnificent city views across the river. 

I would like to thank the sponsors for their generous support, our departmental office staff Anita Littlewood and Carey Ryken-Rapp for their support and for attending to all the many things that matter, all conference speakers for their excellent talks and to all participants for making the week an enjoyable one for everyone. Thanks. It was a great pleasure and privilege for us to host the 26th ACCMCC.

REPORT ON THE SPECIAL SESSION ON APPLICATIONS OF DISCRETE MATHEMATICS 45th ANNUAL MEETING OF THE AUSTRALIAN MATHEMATICAL SOCIETY ANU CANBERRA SEPTEMBER 22-26 2001 Of the fifteen speakers originally scheduled, only one was unable to make it to the meeting because of Ansett woes. Unfortunately, this was my co-organizer Ian Roberts!

The sessions were excellent, including a student session in which all three students were competing for the Neumann prize, a session on security, one on designs, and one on algorithms. In addition, Paulette Lieby held three very well attended Magma demonstrations in a computing lab for all conference participants.

Although none of the students in our session was awarded the Neumann prize, two of them, Nicholas Cavenagh and Michelle Davidson, were responsible for their table winning the ad-hoc after (conference) dinner competition. This was a fun event, far superior to after dinner speeches, and followed a congenial evening of wining and dining at University House on the ANU campus.

The conference was a great success, aided by the proximity of the annual flower show, the art gallery and museum and some excellent restaurants.

Thanks again to all the participants in this special session.

RECENT NEWS OF CMSA MEMBERS:

Nick Hamilton writes from Belgium:

I'm collecting recent theses in Finite Geometry and making them available from here: http://cage.rug.ac.be/~nick/Theses/theses.html The idea is that I'm usually too lazy to request a thesis from a foreign library, or have lost interest by the time it arrives, so I wanted to make recent theses available quickly to myself and other such lazy people.

My interpretation of "Finite Geometry" is not very strict, if a thesis mentions results in finite geometry, or uses finite geometries in a way that might be of interest to finite geometers then it'll probably be fine for the web page. There is more information on how to submit a thesis to me on my home page at http://cage.rug.ac.be/~nick/ I've only just started collecting theses, so I only have 12 so far, but hopefully the number will grow soon.

[Check Nick's home page, above, with lovely pictures of Nick, Jillian and son Edan.]
