El matemàtic argentí va rebre aquest dimecres el prestigiós Premi Abel, concedit per l’Acadèmia de les Ciències i les Lletres Noruega. És la primera vegada que el Premi Abel es concedeix a una persona d’Amèrica Llatina. El premi li ha estat concedit per “les seves contribucions fonamentals en la teoria de la regularitat per Equacions en Derivades Parcials no lineals, inclosos els problemes de frontera lliure i l’equació de Monge-Ampère”. És precisament en aquests temes que ha col·laborat amb els investigadors Xavier Cabré (ICREA-UPC-CRM) i Xavier Ros Oton (ICREA-UB-CRM).
Caffarelli va ser mentor i col·laborador de X. Ros-Oton durant els seus anys de postdoc a la Universitat de Texas a Austin (2014-2017). Les contribucions destacades pel jurat en EDPs i en particular en els problemes de frontera lliure i teoria de la regularitat, són els camps d’estudi de X. Ros-Oton des de fa anys. De fet, en l’article publicat per Nature abans d’ahir, a on expliquen els treballs de Caffarelli, citen el treball de X. Ros-Oton amb Alessandro Figalli (medalla Fields 2018) i Joaquim Serra sobre el problema de Stefan, on perfeccionen els resultats de Caffarelli. L’article, que ha estat acceptat fa pocs dies al Journal of the American Mathematical Society s’explica de manera més divulgativa en aquest article de Quanta Magazine.
Caffarelli també va ser mentor i col·laborador de X. Cabré. La seva col·laboració va començar abans que X. Cabré acabés la seva tesi i en van sortir varis treballs en equacions el·líptiques completament no-lineals. Van escriure conjuntament el llibre ‘Fully Nonlinear Elliptic Equations’ que va ser AMS best-seller. Una altra col·laboració destacada és la seva recerca sobre equacions no-convexes.

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...
