 Eleventh Prairie Discrete Mathematics Workshop

Place and Date | Sponsors | Speakers | Location and Registration | Financial Support for Students | Accommodation | Program | Organizing Committee and Contacts |  


The workshop builds on the success of the ten previous Prairie Discrete Math Workshops, from the first one organized by Shaun Fallat and Brian Alspach and held at the University of Regina in Regina, Saskatchewan, in early October 2003, through the tenth held at Thompson Rivers University in 2013. The intention is to gather together combinatorists from the prairie provinces and nearby locations for a relatively informal workshop. We were lucky to receive permission to hold this 11th edition of the workshop at the Banff International Research Station, which we hope will revitalise the gathering after a brief hiatus last year.
