The course was recorded and streamed from the CRM auditorium from May 29th to June 1st
Dr. Abimbola Abolarinwa, from the University of Lagos in Nigeria, paid a visit to the CRM during his research stay in Spain, as a CIMPA-ICTP scholar. During his visit, Dr. Abolarinwa taught a four-day course that was streamed live from the CRM auditorium. The course, titled Hamilton Ricci Flow and Li-Yau Differential Harnack Inequalities, sought to introduce the fundamentals of Hamilton’s Ricci flow and the theory of Li-Yau Differential Harnack inequalities for the linear heat equation on a static Riemannian manifold.
The course is made possible by the CIMPA-ICTP Research in Pairs project, which allows academics in mathematics from underdeveloped countries to travel to Europe to collaborate with local researchers. The programme is funded by the Centre International de Mathématiques Pures et Appliquées (CIMPA), a nonprofit organisation that promotes research in Mathematics in developing countries. CIMPA strongly supports activities developed in close collaboration with continental mathematical unions, such as Schools in Partnership, the purpose of which is to introduce undergraduate and Master students to research in mathematics. The programme is also made possible by the Abdus Salam International Centre for Theoretical Physics (ICTP), an international research institute for physical and mathematical sciences that explores fundamental scientific questions at the highest level, promotes active engagement with scientists in developing countries, and advances international cooperation through science.
You can find Dr. Abolarinwa’s course on the CIMPA Youtube channel.

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.

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...

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...
