In 1998, number theorists at Université Laval and the University of Maine founded the "Maine/Québec Conference on Number Theory and Related Topics." Since then it has taken place annually on a weekend in early Fall (except 2001, when it was cancelled due to the terrorist attacks that September). We invite number theorists and mathematicians in adjacent fields from New England, eastern Canada, and beyond to speak about their research and discuss ideas for future work. Each year there is a change in venue: odd years at UMaine, even years at U. Laval.
