Workshop on Incidence Geometry and Information Security Applications

Dates: Monday 20th January - Thursday 23rd January 2003.

Location: The Engineering and Mathematics Building at the University of Adelaide. Here is a map of campus.

There is no registration fee. All interested are welcome.

The purpose of this workshop is two-fold. First to discuss recent and current research techniques in the area of incidence geometry. This will mainly, but not exclusively, include finite incidence geometries such as generalized quadrangles, projective and polar spaces, partial geometries and semipartial geometries as well as extremal structures in such geometries. The second purpose it to discuss the application of incidence geometries to problems in information security.

The workshop will include organised sessions of talks on both incidence geometry techniques and information security applications. There will be a scheduled session to discuss open problems, as well as opportunities for informal discussions between participants. It is anticipated that the last day will contain no talks, but be left free for participants to develop joint research projects.

There is no registration fee, and all interested in attending are welcome. There is no expectation of participants presenting a talk, although it is strongly encouraged.

Please feel free to circulate this announcement to anyone whom you feel may be interested.

Speakers include

Professor Frank De Clerk (University of Ghent, Belgium)
Affiliate Associate Professor Christine O'Keefe (CSIRO Mathematical and Information Sciences)
Associate Professor Tim Penttila (University of Western Australia)
Professor Peter Wild (Information Security Group, Royal Hollaway, University of London)


There will be some financial support available to interstate and overseas participants, with graduate students being given priority.
Please indicate if you wish to be considered for support.
Graduate students are especially encouraged to attend.


If you need accommodation, please let us know. Accommodation can be arranged at the Princes Lodge Motel for $60 per night (a 25 minute walk through the parklands to the university), or the Royal Adelaide Hospital Residential Wing which is adjacent to the University of Adelaide.
