History

At the time of creation, IMPA did not have its own headquarters: it was temporarily housed in a room in the headquarters of the

Maurício Peixoto Maurício Matos Peixoto, (April 15, 1921, in Fortaleza, Ceará – April 28, 2019, in Rio de Janeiro), was a Brazilian engineer and mathematician. He pioneered the studies on structural stability, and was the author of Peixoto's theorem. Biogra ...
. Gama's performance at the helm of IMPA, with his experience and wisdom, played a crucial role in the creation and consolidation of the young institute. And Nachbin and Peixoto would later be the first Brazilians invited to lecture at the

, one of the greatest distinctions in a mathematician's career. The academic prestige of IMPA grew from 1957, with the organization of the first Brazilian Colloquium of Mathematics, with about 50 participants. The Colloquium has been taking place every two years since then, in an uninterrupted fashion. Much of Brazilian mathematics was built around it. Also in 1957, IMPA moved to Rua São Clemente, in

(UFRJ), which officially awarded the titles of master and doctor. In 1967, IMPA moved again to a historic building on Rua Luiz de Camões, in the center of Rio de Janeiro, which currently houses the Hélio Oiticica Cultural Center. The following year, with support from the National Bank for Economic Development (future BNDES) and later from the Financier of Studies and Projects (FINEP), in addition to CNPq itself, IMPA expanded its work with Brazilian mathematicians in foreign or in phase PhD in the best foreign institutions. Also in 1968, he assumed the Lindolpho de Carvalho Dias direction, which was to lead the consolidation and growth of the institute over 22 years, with special emphasis on the construction of its own headquarters in the neighborhood of Jardim Botânico (south zone), inaugurated in 1981.

would be consolidated. Recently, symplectic geometry and discrete mathematics have been added. In 1971, IMPA became the first mathematical institution in Brazil with a mandate from the Federal Council of Education to award
master's A master's degree (from Latin ) is an academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice.
and doctoral degrees. The novelty allowed the Master's and PhD program to become a permanent activity. Since then, IMPA's academic postgraduate program has always been awarded the highest grades by the Coordination for Improvement of Higher Level Staff (Capes). IMPA's own headquarters in the Jardim Botânico neighborhood of Rio de Janeiro opened in July 1981, with the International Symposium on Dynamic Systems. On two occasions, Lindolpho de Carvalho Dias was temporarily replaced as the director by mathematician Elon Lages Lima, also elected director for the term 1989 – 1993.

was elected director in 1993. He would hold the position for ten years, a period of remarkable growth in IMPA's international prestige. IMPA's internationalization tendency was accentuated iduring the administration of mathematician César Camacho from 2004 to 2015, a period characterized by the renewal of IMPA's faculty membership, with the hiring of young researchers. In 2005, the Brazilian Maths Olympiad for Public Schools (OBMEP) was created, an initiative of enormous social impact that strongly reaffirms IMPA's commitment to the dissemination of mathematical knowledge.

(IMU). Palis held the position of secretary general during that period. Another groundbreaking fact of its mandate was IMPA's qualification as a Social Organization (SO) in 2000. Six years earlier, a high level evaluation commission set by the Ministry of Science and Technology concluded that “IMPA excellence makes it a model of what a national institute of basic research should be and the conditions to enable it to preserve this excellence must be provided ”. Also during this period, IMPA was formally transferred from CNPq to the Ministry of Science and Technology. That accelerated the studies, started a year and a half earlier, to transform the institute into a Social Organization, which came to fruition a year later. The new model kept the institute in the public sphere, but gave it greater administrative flexibility, as well as more visibility and transparency in its activities. In 2004, IMPA signed a contract with the
