Recognising Excellence in Mathematics
The International Mathematical Union has named the recipients of the 2026 Fields Medal. As the International Mathematical Union states on its website, the Fields Medal is awarded to recognise outstanding mathematical achievement for existing work and for the promise of future achievement. The medal is awarded every four years on the occasion of the International Congress of Mathematicians.
The medals and cash prizes are funded by a trust established by J.C.Fields at the University of Toronto. For 2026, the prize funds from the University of Toronto are supplemented by generous support from the Fields Institute.
The Four Recipients
Yu Deng
For his work in partial differential equations, including the rigorous derivation of the Boltzmann equation from hard-sphere dynamics for rarefied gases, the derivation of wave kinetic equations from nonlinear dispersive systems, and probabilistic approaches to nonlinear Schrodinger dynamics.
John Pardon
For his achievements in symplectic geometry including new approaches to virtual fundamental cycles, Fukaya categories of certain manifolds and counting holomorphic curves, and for his contributions to other areas of geometry and topology, including group actions on 3-manifolds and knot theory.
Jacob Tsimerman
For his contribution in the recasting of o-minimality as a fundamental method of arithmetic and complex algebraic geometry, and his role in the proof of many central conjectures including Griffiths' conjecture on the algebraicity of images of the period maps, and the Andre-Oort conjecture for Siegel modular varieties.
Hong Wang
For her work in harmonic analysis and geometric measure theory, including applications of multiscale and decoupling techniques to the local smoothing conjecture for the planar wave equation, and major advances in Fourier restriction, Falconer distance sets, Furstenberg sets in the plane, and the Kakeya problem in three dimensions.
The Fields Medal Committee
- The Committee is chosen by the Executive Committee of the International Mathematical Union and is normally chaired by the IMU President.
- It is asked to select at least two, with a strong preference for four, Fields Medalists, with regard to representing a diversity of mathematical fields.
- The name of the Chair is made public, while the names of the other Committee members remain anonymous until the award is presented at the Congress.
- A candidate's 40th birthday must not occur before 1 January of the year of the Congress at which the Fields Medals are awarded.
