European Prize in Combinatorics is awarded at EUROCOMB. See here for status and previous winners. At EUROCOMB 21 the international jury consisted from Prof. Béla Bollobás (University of Cambridge and The University of Memphis), Prof. Jaroslav Nešetřil (chair, Charles University, Prague), and Prof. János Pach (Alfréd Rényi Institute of Mathematics, Budapest). The jury decided to award four prizes. In alphabetical order, these are the four laureates:

Budapest University of Technology and Economics

For his numerous profound contributions to discrete mathematics, especially combinatorial algebra, partially ordered sets and combinatorial number theory. His theorem on progression-free sets in (Z_4)^n, proved with Croot and Lev, is a milestone in discrete mathematics.

University of Cambridge

For his deep and important results proved by applying combinatorial methods to problems in harmonic analysis, combinatorial number theory, Ramsey theory, and probability theory. In particular, he proved striking theorems on ancient problems of Littlewood, on the geometry of polynomials, and on fifty-year-old problems of Erdős, Schinzel and Selfridge.

Massachusetts Institute of Technology

For her profound contribution to combinatorics particularly for results on the growth rate of algebraically defined classes, for the solution of an old Erdős, Faudree, Rousseau and Schelp and for the solution of edge-statistics conjecture.

ETH Zürich

For his fundamental contributions to extremal combinatorics and the theory of partially ordered sets, in particular for his proof of the Erdős-Hajnal conjecture for string graphs and the solution of a problem of Brown, Erdős and Sós on extremal numbers of surfaces.
