From March 7th to March 11th two students from Escola Virolai in Barcelona visited the CRM. They joined researchers Tim Myers and Abel Valverde from the Industrial Mathematics group.

The students were able to learn about the project the group is working on, as well as have a glimpse into the life and work of scientists. They also learnt about some mathematical concepts they will reencounter in their future science studies, which both of them are looking forward to pursue.

It is the 3rd year that the Centre de Recerca Matemàtica participates in the “INNOBAT” program in which researchers from the institution host High School students for an immersive experience, offering them a training that involves the student’s approach to real learning environments linked to their choice of baccalaureate and their study and professional orientation, bearing in mind that they are still in the process of deciding on higher studies.

It is a program proposed by the school and supported by CERCA.

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.
