A special issue of Pure and Applied Functional Analysis honors mathematician School of Mathematics Regents' Professor Leonid Bunimovich on his 75th birthday.
Bunimovich's pioneering contributions have shaped modern dynamical systems. He is best known for discovering a fundamental mechanism of chaos in dynamical systems, including systems of chaotic billiards such as the Bunimovich stadium, Bunimovich flowers, and elliptic flowers. Learn about his research in this 2023 news story: Bringing Understanding to Chaotic Dynamics with Billiards, Flowers, and ... Mushrooms?
Georgia Tech School of Mathematics March 16, 2026Research led by Georgia Tech physicist Itamar Kolvin has found that the presence of small imperfections or heterogeneities in materials can have a dual effect on their strength and resilience. While heterogeneities were historically believed to make materials stronger by creating an obstacle course for cracks, the new study shows that in some complex materials, heterogeneities can actually accelerate crack propagation and weaken the overall structure. The findings have implications for how engineers design and reinforce materials to optimize their toughness.
