# Fourteen prizes awarded to European mathematicians at the 9th ECM

The 9th European Congress of Mathematics (9ECM), that takes place from July 15th to 19th in Sevilla, is not only the place to discuss the entire spectrum of contemporary mathematics – it is also the opportunity to bring together the network of members of the EMS and to honour outstanding mathematicians of European nationality or working in Europe, in recognition of excellent contributions to mathematics.

The following sections present an overview of the prizes, followed by a list of the laureates and the citations that accompany the awards.

## EMS Prizes

The EMS prizes were established in 1992. At each ECM up to ten EMS prizes are awarded to early career researchers not older than 35 years at the time of nomination. The award comprises a certificate including the citation and a cash prize of € 5000. The Compositio Mathematica Foundation kindly offered to sponsor half of the prize money. The second half will be sponsored by the publishing house EMS Press.

**Maria Colombo**

Full Professor at École Polytechnique Fédérale de Lausanne

*For breakthrough results in fluid dynamics, optimal transport and kinetic theory, and for her impact on analysis more broadly.*

**Cristiana De Filippis**

Assistant Professor at the University of Parma

*For her outstanding contributions to elliptic regularity, in particular Schauder estimates for nonuniformly elliptic equations and non-differentiable variational integrals, and minima of quasiconvex integrals.*

**Jessica Fintzen**

Full Professor at Universität Bonn and Duke University

*For her transformative work on the representation theory of p-adic groups, in particular for her spectacular proof that Yu’s construction of supercuspidal representations is exhaustive.*

**Nina Holden**

Associate Professor at the Courant Institute of Mathematical Sciences

*For her profound contributions to probability theory and its applications to statistical physics, including results linking Liouville quantum gravity, the Schramm-Loewner evolution, and random triangulations.*

**Thomas Hutchcroft**

Full Professor at California Institute of Technology

*For his revolutionary contributions to probability theory and geometric group theory, in particular to percolation theory on general graphs, using tools from geometry, operator theory, group theory and functional analysis.*

**Jacek Jendrej**

Chargé de recherche at Université Sorbonne Paris Nord

*For his groundbreaking proofs of the soliton resolution conjecture and two-soliton collision problem for equivariant wave maps, developing new approaches using ideas from the theory of dynamical systems to describe the behaviour of solutions near a multi-soliton configuration.*

**Adam Kanigowski**

Associate Professor at the University of Maryland, Full Professor at the Jagiellonian University

*For his outstanding contributions to the spectral classification and the mixing properties of slowly chaotic dynamical systems.*

**Frederick Manners**

Associate Professor at University of California San Diego

*For his remarkable contributions to additive combinatorics and related areas, in particular to the foundations of higher-order Fourier analysis, as well as for miscellaneous other results such as the solution of the pyjama problem.*

**Richard Montgomery**

Associate Professor at the University of Warwick

*For his solution of the Ringel tree packing conjecture, development of distributive absorption techniques with applications to graph embedding problems, and resolution of several classical conjectures of Erdős and others on cycle lengths in sparse graphs using the novel machinery of sublinear expanders.*

**Danylo Radchenko**

Chargé de recherche at Université de Lille

*For the construction of optimal spherical designs and his seminal input in the new field of Fourier interpolation, as well as for his fundamental contributions to the theory of polylogarithms.*

## Felix Klein Prize

Nowadays, mathematics often plays the decisive role in finding solutions to numerous technical, economical and organizational problems. The Felix Klein Prize is to be awarded to a scientist, or a group of at most three scientists, under the age of 38 for using sophisticated methods to give an outstanding solution, which meets with the complete satisfaction of industry, to a concrete and difficult industrial problem. The award comprises a certificate including the citation and a cash prize of €5000. The money for the Prize fund is offered by the Fraunhofer Institute for Industrial Mathematics in Kaiserslautern.

**Fabien Casenave**

Safran Tech, Digital Sciences & Technologies

*For his contributions to the integration of numerical simulation-based design in projects related to physical reduced-order modelling in the aeronautics industry. Fabien Casenave's work lies at the heart of simulation-based design, the integration of which into industrial processes is a key area for ensuring the performance and reliability of tomorrow's engines and meeting the challenges of sustainable development in aeronautics.*

## Otto Neugebauer Prize

The Prize is to be awarded for highly original and influential work in the field of history of mathematics that enhances our understanding of either the development of mathematics or a particular mathematical subject in any period and in any geographical region. The award comprises a certificate including the citation and a cash prize of €5000. The money for the Prize Fund is offered by Springer-Verlag GmbH.

**Reinhard Siegmund-Schultze**

Professor Emeritus at University of Agder, Norway

*For his publications that have helped to shape a new and much richer vision of the contexts of mathematics in the 20th century. A leading social historian of mathematics, Reinhard Siegmund-Schultze has published the outstanding «Mathematicians fleeing from Nazi Germany» and other important books that have brought a major contribution to the study of scientific internationalism, and the times when it collapsed.*

## Paul Lévy Prize in Probability Theory

The Paul Lévy Prize in Probability Theory is a new prize jointly established by the European Mathematical Society, Ecole Polytechnique, the Foundation of Ecole Polytechnique, and the Paul Lévy family, with financial support from BNP Paribas. The Prize is to be awarded to a scientist who has made outstanding contributions to Probability Theory and its Applications and comprises a certificate including the citation and a cash prize of €20.000.

**Jeremy Quastel**

Full Professor at University of Toronto

*He has made major advances in the fields of hydrodynamic theory, stochastic partial differential equations, and integrable probability. Together with his collaborators, he discovered the first exact solutions of the Kardar-Parisi-Zhang (KPZ) equation and more recently constructed the KPZ fixed point - the scale-invariant, integrable Markov process at the centre of an important class of random evolutions of functions.*

## EMS/ECMI Lanczos Prize

The Prize is to be awarded to a mathematician or scientist, or a group of mathematicians and scientists, for the development of outstanding mathematical software with important applications in mathematics, science, engineering, society or industry. The award comprises a certificate and a cash prize of €3000. The money for the Prize fund is jointly offered by the European Mathematical Society and the European Consortium for Mathematics in Industry.

**MUMPS (MUltifrontal Massively Parallel Sparse direct Solver)**

**Patrick Amestoy, Jean-Yves L'Excellent, Theo Mary**

*For their important and widely-used contributions to the numerical solution of sparse linear systems.*
