Prairie Discrete Mathematics Meeting V

(PDMW 2008 Home Page)

May 28, 29 2008

University of Manitoba

All events held in E2-330 and E2-350 (Engineering Building)


PDMW is a semi-regular regional meeting (held approximately annually, and usually in late Summer or early Fall) focussing on pure and applied Combinatorics and Discrete Mathematics, including enumeration, coding theory, graph theory, configurations, design theory, computational discrete mathematics, and applications in physics, engineering and statistics.    While the meeting is geared to participants from the West Central North American region it attracts participants from a wider area. 

The meeting itself consists of a series of one-hour talks by 10-12 speakers.  This year students are encouraged to participate in a casual poster session, and travel support of some form may be available for students and PostDocs who participate (check back later).

Due to the unusual timing for PDMW V this year, it comes immediately prior to WCLAM, the Western Canada Linear Algebra Meeting  -- a similar style of meeting in Linear Algebra, with fewer invited speakers and some contributed talks -- May 30, 31 in the same venue.  Participants with interests in both fields may be interested in staying around and attending both.

(An unrelated meeting in Brandon that will include a Student Workshop on Algebra and Combinatorics will take place a few weeks earlier in nearby Brandon.  Interested participants of PDMW, and particularly students with an interest in this field, may want to check out the Second Annual Conference of the Prairie Network for Research in Mathematical Science May 7, 8, 9)

Those making planning to pack multiple meetings into a single trip may want to take notice of the Second Joint Canada-France Congress taking place at the Universite du Quebec a Montreal June 1-5, a meeting subsuming the Annual CMS Summer meeting, the annual meetings of CAIMS and also of MITACS.  Of interest to PDMW attendees, this meeting will have a Session on Algebraic combinatorics and a MITACS student poster session, with funds available to defray the cost of posters (Note the April 15 Deadline!).  Their web page also references the congress held just prior in Ottawa by the Société Française de Statistique (SFdS) and the Statistical Society of Canada (SSC).

A brief history of PDMW

In prehistory there were meetings loosely referred to as "combinatorial potlatches", involving universities in British Columbia and Washington.  PDMW was proposed by Brian Alspach as a generalization of the concept.

PDMW I:  University of Regina, 2002
PDMW II:  University of Lethbridge, 2003
PDMW III: University of Winnipeg, Aug. 25, 26 2005
PDMW IV: Lethbridge, Aug. 1, 2 2006 (Held in honour of Jim Liu after his tragic death)

In previous years PDMW has been brought to you by the generous support of PIMS and the host university.   Support for this meeting is currently pending.

After 10 both days
E2 - 330
Refreshments served starting at 10 both days, available during all breaks between talks.
During all breaks
Poster Session
E2 - 330
There is no formal time designated as a "Poster Session".  Attendees may browse the posters during all breaks between talks, lunch, and before/after each day's events.  Participants should remainavailable to answer questions at such times, and be physically present at their poster at least twice each day.

Student participation

PDMW  encourages student attendance.  Graduate students and PostDocs, in particular, are encouraged to present posters.  The style of the session is passive:  Posters will remain up in the refreshment area throughout the meetings for casual browsing, with presenters available at their poster to field questions at designated times between regular sessions, but there will be no specific block of time allotted for "poster presentations".   This is a particularly good venue for grad students, undergraduate students reporting on summer research projects, and attendees not on the speaker list wishing to disseminate some aspect of their current work, which they judge suitable for such a venue.

Partial travel support is being sought to support students or PostDocs who present posters (if such materializes it will be announced here).  Students and their supervisors are also encouraged to take advantage of travel funds available through their home departments and/or faculties, which often depends upon the students giving some sort of presentation (such as a poster).
