Overview

The Ontario Combinatorics Workshop is an annual meeting for researchers working in combinatorics from Ontario and surrounding areas to gather and share their latest research developments. The objective of this meeting is to have an atmosphere conducive to research discussion and collaboration. The setting of the meeting is informal to provide a friendly environment for students and post-doctoral fellows to present their results, to exchange ideas, and to gain exposure to various topics in combinatorics. It is also a place where students and faculties meet, which may foster future collaborations.

Format
The Ontario Combinatorics Workshop will be a two-day event consisting of three invited talks and a few sessions contributed talks.

Peter Rodney Memorial Book Prize:
The prize will go to the student who gives the best talk in the workshop in honour of Dr. Peter Rodney (1965-1995).

Invited speakers:
Aleksandar Jurišic, Professor, Faculty of Computer and Information Science University of Ljubljana, Slovenia
Kevin Purbhoo Associate Professor, Department of Combinatorial and Optimization University of Waterloo
Andrew Rechnitzer Associate Professor, Mathematics Department University of British Columbia
