IMO PROBLEMS, THEOREMS, AND METHODS (IN 4 VOLUMES)

The problems in the International Mathematical Olympiad (IMO) are not only novel and interesting but also deeply rooted in profound mathematical context. The team at the International Mathematical Olympiad Research Center at East China Normal University has compiled and studied problems from past IMOs, dividing them into four volumes based on the mathematical fields involved: algebra, geometry, number theory, and combinatorics. These volumes are collectively titled "IMO Problems, Theorems, and Methods".
