- Mathematician László Lovász received the 2025 Erasmus Medal from the Academia Europaea yesterday at the PRBB in Barcelona, where he delivered the lecture “The Beauty of Mathematics”.
-
This Wednesday, October 16, Hungarian mathematician László Lovász received the 2025 Erasmus Medal, the highest distinction awarded by the Academia Europaea, during a ceremony held at the Barcelona Biomedical Research Park (PRBB) as part of the annual Building Bridges 2025 conference.
The award recognises his exceptional career in discrete mathematics and computer science, as well as his significant contributions to European scientific culture. A former President of the Hungarian Academy of Sciences, Professor Emeritus at Eötvös Loránd University (ELTE), and Research Professor at the HUN-REN Alfréd Rényi Institute of Mathematics, Lovász is regarded as one of the most influential theorists of his generation.

The Erasmus Medal citation described Lovász as “a towering mathematician of our age”, whose work has transformed the landscape of discrete mathematics and its links with classical branches of pure and applied mathematics. Over six decades, his elegant and powerful ideas have solved major open problems and created entirely new subfields, from the Lovász Local Lemma and the proofs of the weak perfect graph and Kneser conjectures to the Lenstra–Lenstra–Lovász lattice reduction algorithm, the ellipsoid method in combinatorial optimisation, and the theory of graph limits.
The ceremony, introduced by Jaume Bertranpetit, Academic Director of the Academia Europaea Barcelona Hub, featured a laudation by János Pach (Rényi Institute and EPFL), who outlined Lovász’s long-standing influence across mathematics and computer science. The event concluded with Lovász’s Erasmus Lecture, titled “The Beauty of Mathematics”, a reflection on the inner elegance and coherence that connect seemingly distant branches of the mathematical sciences.
The event was attended by Guillem Perarnau, Marc Noy, and Oriol Serra, researchers at the Universitat Politècnica de Catalunya (UPC) and affiliated members of the CRM, along with Carme Cascante, Director of the CRM, who represented the centre at the ceremony.
The Erasmus Medal is one of the most prestigious honors granted by the Academia Europaea for outstanding scientific achievements. With this award, László Lovász joins a distinguished group of laureates who have strengthened the bridges between science, technology, the humanities, and society.

Jagged walls and unknown edges: a workshop on free boundary problems
From 2 to 6 November, the Workshop on Free Boundary Problems brought together more than fifty registered participants from institutions in eleven countries at the CRM. Over five days they heard 21 talks on elliptic and parabolic free boundaries and on geometric measure theory and harmonic analysis in rough domains, with speakers including Guy David, Svitlana Mayboroda, Susanna Terracini and Robin Neumayer. The workshop was the second intensive week of the Intensive Research Programme on Analysis of Free Boundary Problems, which continues at the CRM until 4 December.
The CRM exhibition ‘Les matemàtiques de Gaudí’ moves to the University of Barcelona
After its October run at the UAB, the exhibition Les matemàtiques de Gaudí, produced by the CRM, can be seen at the University of Barcelona’s CRAI Biblioteca de Matemàtiques i Informàtica from 2 to 30 November 2026.
Advanced Course on Free Boundary Problems Opens the Intensive Weeks of the IRP
From 26 to 30 October, around forty researchers attended the Advanced Course on Free Boundary Problems at the CRM, three seven-hour mini-courses given by Bozhidar Velichkov (Università di Pisa), Max Engelstein (University of Minnesota) and Zihui Zhao (Johns Hopkins University). The course was the first of the two intensive weeks of the Intensive Research Programme on Analysis of Free Boundary Problems, which runs until 4 December.
El CRM rep els estudiants de la prova de nivell de Bojos per les Matemàtiques 2027
Els aspirants a Bojos per les Matemàtiques 2027 van visitar el Centre de Recerca Matemàtica (CRM) dissabte 24 d’octubre, després de fer la prova de nivell a la Facultat de Ciències i Biociències de la UAB. En acabat, Tomás Sanz (UB-CRM) els va explicar què té a veure l’escalfament d’una barra de ferro amb els àudios de WhatsApp.
Eight CRM Researchers in the 2026 Stanford-Elsevier List of Highly Cited Scientists
The Centre de Recerca Matemàtica (CRM) has eight researchers in the 2026 update of the Stanford-Elsevier ranking of highly cited scientists, which John P. A. Ioannidis (Stanford University) and Jeroen Baas (Elsevier) compile from Scopus data. Xavier Cabré, Álvaro Corral, Tim Myers, Xavier Ros-Oton, Sergey Tikhonov and Xavier Tolsa appear both in the career-long ranking and in the one for 2025, and Diego Vidaurre and Simeon Ball in the 2025 ranking.
Fish schools and growing tissues: a workshop on how collective behaviour emerges
The Centre de Recerca Matemàtica (CRM) organised the Barcelona Workshop on Kinetic and Macroscopic Models in Biology with Friends II, held from 7 to 10 September at the Institut d’Estudis Catalans. More than thirty researchers discussed how order at the scale of tissues and animal groups arises from local interactions between individuals, in a programme that included talks by CRM researchers Daria Stepanova and Juan Arellano-Tintó. Two of the speakers, James Sharpe (EMBL Barcelona) and Chiara Villa (CNRS, Université Paris Cité), talked to the CRM about their research.

Almost every automaton can be reset with a short word
Guillaume Chapuy (Université Paris Cité, CNRS) and Guillem Perarnau (UPC, CRM) have shown that a random finite automaton with n states can, with high probability, be reset by a word of length of order √n log n. The result, published in ACM Transactions on Algorithms, pins the exponent at 1/2, the lower end of a decade of numerical estimates, and addresses the random version of the synchronization problem behind a conjecture Ján Černý posed in 1964 and which still remains open.
