Thank you to all the participants for making the conference interesting and enjoyable!

A special thanks go to Aramark Food Services at the University of Regina and to their staff for doing such a fantastic job of catering all of the breakfasts, lunches, and coffee breaks for the conference, and to Residence Services at the University of Regina for all of their assistance in making our visitor's stay on campus a comfortable one.

As proposed at the conference, we are going to collect a list of open problems concerning Association Schemes and Scheme Rings to be posted online and distributed to the participants. Open problems can be submitted by email to either of the organizers. The submission deadline for the Regina List of Open Problems in Association Schemes, 2008 from conference participants is October 11, 2008.

Conference Overview:
Research on the subject of association schemes and scheme rings has seen rapid growth recently, with ideas from graph theory and design theory mixing with those of group theory and representation theory to produce a rich and vibrant field of research. Although the diversity of approaches to association schemes and scheme rings is clearly a strength and an exciting aspect of this study, it also makes it difficult for researchers with one perspective to be aware of and fully understand the work that takes a different approach. Further, there is a high potential for ideas from representation theory and group theory to have an impact on the subject of association schemes and scheme rings. The main objective of this conference is to bring together researchers interested in association schemes from both the combinatorial and the representation-theoretic perspectives.

All participants will be encouraged to invite any interested graduate students and post-doctoral researchers in their groups. Participants from these groups may apply for support to cover some of their local expenses.

The deadline for applying for this extra support is April 30, 2008.

Contributed Talks:
Attendees to the conference are encouraged to give a contributed talk of either 25 or 50 minutes duration. If you wish to give a contributed talk, indicate this when you register.
