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.

ADA: Decoding Brain Signals Misaligned in Time
The study addresses a key limitation of current brain decoding techniques: the difficulty of interpreting internal mental processes whose temporal dynamics vary from trial to trial.Decoding what is happening in a person’s mind from their brain activity is one of the...
Rare curves, many points: Christophe Ritzenthaler and Rachel Pries on their research and the work around it
Christophe Ritzenthaler (Université de Rennes) and Rachel Pries (Colorado State University) both work on curves over finite fields: he hunts curves with as many points as possible, she hunts curves that almost never occur. In conversation with the CRM during their...
