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.

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...
