El CRM va participar en la 30a edició de la Setmana de la Ciència amb una ruta guiada que va combinar les biografies de dones matemàtiques amb obres d’art del centre, connectant ciència, història i creació artística.

El 12 de novembre, el Centre de Recerca Matemàtica va obrir les portes a visitants que van recórrer els passadissos del centre amb una missió clara: descobrir les històries de dones que han transformat les matemàtiques i deixar-se sorprendre per l’art que habita entre les equacions.

La ruta Dones, formes i pensament va combinar l’exposició Figures visibles amb obres artístiques del centre, guiada per Pau Varela i Natalia Vallina, del Departament de Comunicació, i Javier Guillán, estudiant de doctorat al CRM. Durant una hora, els participants van passejar per les biografies d’Emmy Noether, Maryam Mirzakhani, Maria Assumpció Català i altres matemàtiques que van obrir camí en contextos sovint hostils. Les explicacions van anar més enllà dels teoremes: qui eren aquestes dones, què van haver de superar, i com les seves idees ressonen encara avui en la recerca actual.

El recorregut també es va aturar davant de dues pintures Geomètric de Mercè Rodoreda, una faceta poc coneguda de l’escriptora, i les escultures Creation de John Robinson i Bonds of Friendship de Jeff Robinson, peces que conviden a pensar en simetries, topologia i la construcció del coneixement des d’una mirada que no distingeix entre art i ciència.

Una activitat emmarcada en la 30a edició de la Setmana de la Ciència que reivindica el que el CRM fa cada dia: connectar la recerca matemàtica amb el món, i recordar que darrere de cada teoria hi ha sempre una persona.

Jagged walls and unknown edges: a workshop on free boundary problems

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.

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.

Eight CRM Researchers in the 2026 Stanford-Elsevier List of Highly Cited Scientists

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

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

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.
