The theme for the 2026 IDM is ”Mathematics and Hope”.

Connecting hope and mathematics creates opportunities for deeper insight and knowledge. Mathematics gives us hope to understand reality and truth clearly, learn cooperation, find win-win strategies, and more.

Eight people stand or sit in a circle, some wearing head coverings. Each person holds a small triangular slice of watermelon (one eight of a circle). The slices are arranged so that their tips point toward the center.

This year's IDM poster is now available! It's based on a Penrose Tiling and comes in two versions: full-color, or black-and-white one which you and your friends can color to add your creative touch and make it unique.

Four children stand hand in hand outside on a village street. Their hands are alternatively held up or down so their arms form a sine wave-like pattern.
