Luis Caffarelli awarded 2023 Abel Prize for mathematics.

Argentinian mathematician Luis Caffarelli has won the 2023 Abel Prize for his work on equations that are important for describing physical phenomena, such as how ice melts and fluids flow. Caffarelli is the first person born in South America to win the award. Many of Caffarelli’s most celebrated results have to do with the regularity of the solutions of so-called partial differential equations, which are among the most important equations in maths and physics.
