The Ontario Combinatorics Workshop (OCW) is a conference where researchers working in combinatorics gather to share their research interests and exchange ideas. This workshop aims at providing a friendly environment for graduate students to give conference presentations, learn about different topics in combinatorics, and meet combinatorialists from Ontario and surrounding areas. The workshop consists of three one-hour invited talks, and several sessions of 20-minute contributed talks.

Accommodation

Queen’s University offers only double rooms (shared bathroom between the two private bedrooms) for $151 (taxes included). Before booking, please coordinate with a roommate who is also attending. Together, make one single reservation. If you are applying for student accommodation support, please indicate your choice of roommate in your application, and we will assign roommates. You may also choose to independently book one double room, with no roommate, paying the whole cost.

For those guests reserving and paying for themselves, you must book via this link in order to book within our room block. You will be asked for a credit card to hold the reservation, but will not be charged until Check-In. If you have questions about accommodations, please email Dr. Erin Meger

For those who would prefer to stay in a hotel, Queen’s University recommends the Marriott Kingston. There is no conference rate for this conference, so rates may vary. There are many other local boutique and chain hotels in the area. Please feel free to email Dr. Erin Meger for any other questions about the local area.

Peter Rodney Book Prize

The best talk given by a student at the Ontario Combinatorics Workshop will be awarded the Peter Rodney Memorial Book Prize. This prize of a book and memorial book plate is given in honour of Dr. Peter Rodney (1965-1995).

Dr. Rodney graduated from McGill University, and then obtained his Masters and Ph.D degrees in Combinatorics, from the University of Toronto. He graduated in 1993 and went on to do postdoctoral research at the University of Vermont. He then continued to work in both the public and private sectors, using discrete mathematics, cryptography, and number theory.

Dr. Rodney had a deep appreciation for probability theory and was an avid card player. He died unexpectedly at the age of 30. His friends and family created a fund in his memory whose proceeds finance this book prize.
