Instituto Nacional de Matemática Pura e Aplicada

The Instituto de Matemática Pura e Aplicada ( IMPA ) is a 1952 Brazilian based National Research Institute for Mathematics in Rio de Janeiro. The first director was the astronomer Lélio Gama. The founding members also included Mauricio Peixoto and Leopoldo Nachbin. On Peixoto also the focus goes back in the field of dynamical systems. 1957 took place the first Brazilian Mathematical Colloquia here, which take place every two years since then, up to 1200 participants. In addition to research and post-doctoral program is also in collaboration with the University of Rio programs for graduate and undergraduate students.

Since 1957 it was located at Rua São Clemente in Botafogo, 1967 in a historic building of Luís de Camões Street and from 1981 in a new building in the Botanical Garden (Dona Castorina Road 110).

On IMPA investigated, among others, Jean -Christophe Yoccoz, Stephen Smale (which he started his own research on dynamical systems and the generalized Poincaré conjecture in five or more dimensions proved ). Members were Welington de Melo, Artur Avila, Marcelo Viana, Jacob Palis and Manfredo do Carmo, Elon Lages Lima ( born 1929 ), Felipe Voloch and Paulo Ribenboim (from 1957), but mainly William Meeks, Harold William Rosenberg. Both Palis and Lima were temporarily directors.

The focus was initially functional analysis, differential topology and dynamical systems, in the 1970s came algebraic geometry and differential geometry, probability theory, mathematical statistics, operations research and mathematical economics and later added Partial Differential Equations, Computer Graphics and hydrodynamics.

It is since its founding in 1969, the seat of the Brazilian Mathematical Society from 1990 to 1998 and was the seat of the International Mathematical Union.

They also own textbook series out ( Euclides, Matematica Universitaria ).
