Future workshop and conference announcements
SIGMAP'10, Oaxaca, Mexico
The workshop Symmetry in Graphs, Maps and Polytopes, SIGMAP'10, will be held in Oaxaca, Mexico, from June 20th to June 25th, 2010.
Oaxaca is a beautiful colonial city in the Mexican interior in close proximity to many interesting archaeological sites. It is famous for its colourful markets and interesting cuisine (boasting the best mezcal, Chocolate Street and the delicious chapulines). There is an international airport in Oaxaca. Alternatively, you could fly to Mexico City and take a six hour bus ride to Oaxaca. More information on travel to Oaxaca and the accommodation will be available on the conference website soon.
In 1998 the first SIGMAC workshop was organized by Steve Wilson in Flagstaff, Arizona. Since then, the workshops have been organized every four years, with workshops in 2002 and 2006 held in Aveiro, Portugal, organized by Antonio Breda d'Azevedo.
SIGMAP workshops are now part of the cycle of meetings that combinatorial geometers have every year, with 4 years periods, in New Zealand (in the years congruent to 0 mod 4), Slovakia (1 mod 4) and Slovenia (3 mod 4).
This workshop, the fourth in its series, will convene researchers interested in geometric, topological and combinatorial objects having large symmetry (automorphism) groups.
The program will consist of 50-minute talks by invited speakers, and 20 minute contributed talks, a problem session, an outing, a banquet and wealth of time for conversation. The contributions are to be related to one of the following topics:
- Group actions on graphs
- Regular maps and hypermaps
- Highly symmetric polytopes
- Symmetric higher-dimensional complexes
- Automorphism groups of Riemann surfaces and algebraic curves
See you in Oaxaca!

Professor Ralph Gordon Stanton passed away
Ralph Gordon Stanton, Distinguished Professor, Computer Science, passed away on April 21, 2010, in St Boniface hospital, at the age of 86. Stanton always preferred an uncomplicated life, and asked for little more than a shelf of good books, his stamp collection, a little good food, and some congenial company. His 61 year academic career was marked by many achievements and honours, and he will long be remembered for his teaching, mentorship and supervisory skills, and for his philanthropic generosity.
In Memory Of Ralph Gordon Stanton.
Successful workshop on the Hadamard Maximal Determinant Problem
A workshop on the Hadamard Maximal Determinant Problem was held 13-17 May, 2010, within the Mathematical Sciences Institute at the Australian National University.
The workshop began on Thursday with ANU MSI's traditional afternoon tea and a departmental colloquium by Professor Jennifer Seberry, who gave a well attended and received presentation about her many contributions to the early days of Hadamard matrices and computing.
Friday and Saturday were full days of talks and workshop about the maximal determinant problem and the latest developments in Hadamard matrices. Several participants who had primarily worked on either the maximal determinant problem, or on Hadamard orders specifically, enjoying learning about each other's perspectives. The days were interspersed with delicious morning and afternoon teas.
The workshop offered other opportunities for pleasant dining, with dinners at the China Tea House in Dickson on Thursday, at Boffin's restaurant in University House on Friday evening and at Fekerte's Ethiopian Cuisine on Saturday; as well as a relaxing lunch at Spicy Ginger Cafe in Acton on Saturday afternoon.
On Monday the workshop wrapped up with a seminar by Dr William Orrick on a problem which subsumes both the Hadamard Conjecture and the maximal determinant problem: namely the `spectrum problem' for binary matrices, presented in the seminar series of the Computational Mathematics Group within the Centre for Mathematics and Its Applications.
Funding from the ARC Centre of Excellence MASCOS (Mathematics and Statistics of Complex Systems) and the ANU-INRIA Associate Team ANC (Algorithms, Numbers, Computing) allowed our international visitors to be present and for visitors to stay on campus at University House and Liversidge Court Apartments for this very enjoyable and productive workshop.
Speakers at the workshop and their topics were:
- Professor Richard Brent, ANU `Decomposing Gram Matrices'
- Professor Kathryn Horadam, RMIT `Hadamard Matrices and Their Applications: an update'
- Dr Paul Leopardi, ANU `Amicability graphs and Clifford algebras'
- Professor Charles Little, Massey University `A possible approach to the Hadamard Conjecture using Coding Theory'
- Dr William Orrick, Indiana University, Bloomington. `Codes and the structure of Hadamard matrices' and `Range and distribution of determinants of binary matrices'
- Dr Judy-anne Osborn, ANU `Visualizing searches for Maximal Determinant Matrices'
- Professor Jennifer Seberry, University of Wollongong, `Progress in Hadamard Matrices via Computers' and `How Progress in Orthogonal Designs and Sequences have led to Progress in Hadamard Matrices via Computers'
- Dr Paul Zimmermann, INRIA, Nancy `An Implementation of Orrick's Algorithm'
