Commemorates the 25th anniversary of the Centre de Recherches Mathematiques (CRM) - a national institute for research in the mathematical sciences in Canada. This title includes contributions by scientists who have been closely involved with the CRM. It covers various topics in pure and applied mathematics, statistics, and mathematical biology.
