On November 6th, the 16th edition of the Brazilian Public Schools Mathematics Olympiad (OBMEP) ended.  Despite the uncertainties arising from the pandemic, just under 18 million students from the sixth year of elementary school (children aged eleven) to the third year of high school (teenagers aged 17) participated in the olympiad this year.

Brazil is a nation of contrasts.  On the one hand, the country was admitted, in 2018, to the select Group 5 of the International Mathematical Union (IMU), which gathers the main leaders in the world in this area.  In addition to Brazil, it includes, in alphabetical order, Canada, China, France, Germany, Israel, Italy, Japan, Russia the United Kingdom and the United States.

On the other hand, according to the Programme for International Student Assessment (PISA) of the Organisation for Economic Co-operation and Development (OECD), Brazilian students perform well below the average of OECD students.  In 2018, the score of Brazilian students in mathematics was 384, significantly below the OECD average (489).  The same difference is observed in sciences (404, cf. 489) and in reading (413, cf. 487).  Performance in mathematics puts Brazilian students behind most other Latin American countries (Chile 417, Uruguay 418, Mexico 409, Costa Rica 402, Colombia 391, Peru 400), and just ahead of Argentina (379).

A more detailed analysis (OECD, 2019) reveals a regional disparity and a large variation by administrative dependency.  In 2018, the PISA average score in mathematics in the North East region of the country was 363, in contrast with 401 in the South region.  The PISA score in county schools was 314, while it was 374 for state schools, 469 for federal schools, and 473 for private schools.  In Brazil there is clearly a relationship between socio-economic status and PISA results (OECD, 2019).

As the OBMEP's problems do not measure knowledge in mathematics, but creativity, abstraction and reasoning skills, the olympiad reveals every year students with talent for the exact sciences.  In the year following the olympiad, the 7,475 medal winners receive a grant from the National Council for Scientific and Technological Development (CNPq) to participate in a training program that teaches mathematics through problem solving and encourages students to continue their studies at a university.  Many of them thus become the first member of their families to go into higher education.

This is not the only benefit of OBMEP to the teaching of mathematics in the country.  With the olympiads, an increasing number of university mathematics professors are involved in basic education, either in the student training programme described above, or in similar programmes for basic education teachers.

In addition, OBMEP has encouraged university professors to write books for basic education, to contribute to the OBMEP Portal, which contains videos, theoretical booklets, exercise books and tests covering all basic mathematics education curriculum, and to help in establishing curriculum itineraries for high schools.

We thus hope to gradually improve the teaching of elementary mathematics in Brazil, supported by the quality of the scientific research in the country.

The 2022 ICM Noether Lecturer: Marie-France Vignéras

The 2022 ICM Emmy Noether Lecture will be delivered by Marie-France Vignéras, Professor Emeritus of the Institut de Mathématiques de Jussieu, Paris, France.

A native of France, Marie-France Vignéras grew up in Sénégal and subsequently studied at the Université de Bordeaux, where she completed her PhD in 1974 on the arithmetic of quaternion algebras, under the supervision of Jacques Martinet.  With stints elsewhere in France, and at research institutes around the world, she has spent most of her career at the Université Paris 7 (now called IMJ at Université de Paris).  She was a plenary speaker at the European Congress of Mathematics in 2000 and an invited speaker at the ICM in 2002.  She is the recipient of the Médaille Albert Châtelet, the Silver Medal of the CNRS, the Humboldt Prize and the Petit d'Ormoy Prize of the Académie des Sciences de Paris.

Marie-France Vignéras has been a leading number theorist for over four decades.  Early career highlights include her 1978 proof of the existence of non-isometric closed hyperbolic surfaces with the same spectrum, as a consequence of her number-theoretic results.  This answered negatively the question of Mark Kac, popularly posed as “Can one hear the shape of a drum?”, for hyperbolic surfaces.  Much of her later work has centered around representation theory in arithmetics, with many deep contributions, from her proof of a mod-l local Langlands correspondence for GL(n) compatible with the complex local Langlands correspondence, to her recent work classifying mod p representations of p-adic reductive groups.  Through her work she has had a profound influence on development of the Langlands program and the representation theory of p-adic groups.  She has also had a huge influence on the mathematical community, e.g., through mentoring, where notable PhD students include Jean-Loup Waldspurger and Jean-François Dat.

IDM 2022 International Day of Mathematics

The 2022 IDM Event Map.  The 2022 IDM Event Map is now online.  Anyone planning an IDM celebration in 2022 is invited to make a pre-announcement on the IDM website; details on the planned event can be added later.

IDM classroom activities and larger events.  The IDM Governing Board hopes to increase significantly the number of schools celebrating the IDM, either in the classroom, or through a larger event.  One way to interpret the 2022 IDM theme “Mathematics Unites” is the fact that the whole planet shares the same mathematical language.  To illustrate this through a school activity, some proofs without words have been added to the material proposed for classroom activities.  The IDM Governing Board needs your help for reaching the schools and school networks of your country: invite them to celebrate and to join the IDM community by registering to the IDM newsletter.

IDM Ambassadors.  The IDM Governing Board is looking for IDM Ambassadors in all countries of the world to help increase celebrating the IDM.  If you are interested to become an IDM Ambassador, please send a message to  IDM Ambassadors will be acknowledge on the IDM website.
