On February 24th, 2022, the Russian Federation launched an invasion into the territory of Ukraine. As of March 4th, the ensuing war, that has already caused a massive loss in lives and the displacement of hundreds of thousands of people, is still in progress even in the face of strong international protests and the sanctions issued against Russia.
The Centre de Recerca Matemàtica condemns the invasion of Ukraine by Russian military forces, joining the numerous research institutions, universities and organizations calling for an urgent end to the violence. Mathematicians, and scientists in general, strongly believe in cooperation as a means to advance society. We witness with dire concern the damage caused by war to science, education, academics, and international cooperation among researchers, as well as society at large.
Our thoughts are with all the members from the Ukrainian mathematical community and the rest of the Ukrainian population, whose lives and livelihoods have been irretrievably affected by the conflict. We also stand in support with the numerous Russian mathematicians that have publicly spoken against the war to denounce this aggression.
We hope for a swift solution for this terrible crisis.

Ho Chi Minh City hosts the first SEAMS School on applying mathematics to real-world problems
More than fifty students from six countries spent a week at the University of Science, VNU-HCM, learning how mathematics gets used outside a mathematics department. CRM researcher Tim Myers co-organised the school and lectured on moving boundary problems. The...
A single ball on a fixed table can compute: Eva Miranda and Isaac Ramos prove that two-dimensional billiards are Turing complete
Eva Miranda (UPC, CRM) and Isaac Ramos (ETH Zürich) show that a point particle bouncing inside a planar table with fixed walls can simulate a universal Turing machine, settling a question Cristopher Moore left open in 1990. The result grew out of a master’s project...

The CRM organises the 2026 Barcelona Summer School for Advanced Modeling of Behavior
The Centre de Recerca Matemàtica held the sixth edition of BAMB!, the Barcelona Summer School for Advanced Modeling of Behavior, from 12 to 23 July 2026 at the Parc de Recerca Biomèdica de Barcelona. Thirty early-career researchers from fourteen countries followed...
Mallorca’s 1820 plague did not behave like a classic bubonic outbreak, study finds
A study in PNAS by Pere Puig (UAB, CRM) and Joana Maria Pujadas-Mora (UOC, ICREA) reports what happens when the daily health records kept in Son Servera and Capdepera during the 1820 outbreak are analysed with a Bayesian epidemiological model: an unusually short...
A recent study quantifies the vegetable production potential of Barcelona’s rooftops
A study published in Cities by researchers at ICTA-UAB, with collaboration from the CRM's Knowledge Transfer Unit, estimates that 65 hectares of municipal rooftop could supply 31% of the tomatoes consumed in Barcelona each year.Barcelona has 65 hectares of rooftop...
