Djairo Guedes de Figueiredo (academic signature: D. G. De Figueiredo, born on 2 April 1934, in Limoeiro do Norte) is a Brazilian mathematician noted for his researches on differential equations, elliptic operators, and calculus of variations. [1] He is considered the greatest analyst from Brazil. [2] He was the president of the Brazilian Mathematical Society from 1977 to 1979. [3]
Figueiredo is a well-known figure among mathematicians in analysis and differential equations and among Brazilian students in physics, engineering and mathematics. He has received many Brazilian national and international prizes, both for his research in pure mathematics and also for his popular mathematics textbooks (about analysis and differential equations) and expository writing papers. In 1995 he received the National Order of Scientific Merit [1] and in 2004 the title of "Doctor Honoris Causa" from the Federal University of Paraíba.
In 2009, he became a member of the National Academy of Science of Buenos Aires. In 2011, he became the first Brazilian to receive a gold medal from the Telesio-Galilei Academy of Sciences "for his great contribution to Mathematics, especially to the theory of elliptical partial differential equations". [4]
He was a Ph.D. student of Louis Nirenberg at New York University, [5] and is currently a titular professor at UNICAMP, a position he earned in 1989.[ citation needed ]
He is a recipient of Brazil's National Order of Scientific Merit in mathematics (1995). [6] Since 1969 he has been a member of the Brazilian Academy of Sciences. [7]
The book Selected Papers of Djairo Guedes Figueiredo has been published by Springer, as part of the collection Selected Works of Outstanding Brazilian Mathematicians (Google Preview).
The Instituto Nacional de Matemática Pura e Aplicada is considered to be the foremost research and educational institution of Brazil in the area of mathematics. It is located in the city of Rio de Janeiro, and was formerly known simply as Instituto de Matemática Pura e Aplicada (IMPA), whose abbreviation remains in use.

The Brazilian Mathematical Society is a professional association founded in 1969 at Instituto de Matemática Pura e Aplicada to promote mathematics education in Brazil.
Fernando Codá dos Santos Cavalcanti Marques is a Brazilian mathematician working mainly in geometry, topology, partial differential equations and Morse theory. He is a professor at Princeton University. In 2012, together with André Neves, he proved the Willmore conjecture. Since then, among proving other important conjectures, Marques and Neves greatly extended Almgren–Pitts min-max theory to prove theorems about minimal surfaces.
