Second Prairie Discrete Mathematics Workshop

Second Prairie Discrete Mathematics Workshop

This workshop builds on the success of the First Prairie Discrete Math Workshop organized by Shaun Fallat and Brian Alspach and held at the University of Regina in Regina, Saskatchewan, in early October 2003. The intention is to hold workshops on an annual basis at various universities for the purpose of getting together Combinatorists from (at least) Manitoba, Saskatchewan and Alberta and adjacent States for a relatively informal workshop.

University of Lethbridge, Lethbridge, Alberta, Friday October 1 - Sunday October 3, 2004.

Faculty of Arts & Science, University of Lethbridge

Location and Registration

All events will be held on the campus of the University of Lethbridge, Lethbridge, Alberta, Canada. To reach the University: fly to Lethbridge, or fly to Calgary and drive for 2.5 hours, taking Highway 2 south to Ft. MacLeod and then Highway 3 east from there, or fly to Great Falls and drive for 3.5 hours, taking the highway north. If you need a ride from the Lethbridge airport please contact Joy Morris, joy at cs dot uleth dot ca. Once in Lethbridge proceed to the west side of town since the University is located on the western coulee banks of the Old Man River. On Highway 3 look for the Highway 25 exit south. The sessions are in the main building (University Hall).

On Friday parking for participants is available at the north end of the West parking lot by Anderson Hall; if you park here there will be no parking fee for workshop participants, but please follow the signs. See campus map. On Saturday and Sunday parking is free at the north lot which is much closer to University Hall.

Note that scenic Waterton National Park in the Rocky Mountains, about an hour and twenty minutes drive south-west of Lethbridge, is a possible outing for those wishing to extend their stay with some pre or post workshop sightseeing.

A number of rooms (15) are being held for the time being for the workshop at the Lethbridge Lodge, where University visitors frequently stay. To get the special reduced rate of $90 plus taxes per night please mention that you are attending the Prairie Discrete Math Workshop. This hotel is located downtown, about a 30 minutes walk from the University. There are no hotels in West Lethbridge or closer to the University, however, there are many other hotels and motels available, such as in the Days Inn. To check out alternatives visit alternate accommodation. Hotels along Mayor Magrath Drive are relatively far away and you would require vehicle transportation to get to the University.

If you will be attending please register here:

There is no registration fee, but we would like to know who is planning to attend.

Program

The talks are in rooms on the sixth (main) level of University Hall, the long main signature building on the east side of campus. The talks are one floor up from the department office (D526), faculty offices, lounge and computer labs on the fifth level.
