Welington Celso de Melo (17 November 1946 – 21 December 2016) was a Brazilian mathematician. Known for his contributions to dynamical systems theory, he served as full professor at Instituto Nacional de Matemática Pura e Aplicada from 1980 to 2016. Melo wrote numerous papers, one being a complete description of the topological behavior of 1-dimensional real dynamical systems (co-authored with Marco Martens and Sebastian van Strien).[1] He proved the global hyperbolicity of renormalization for Cr unimodal maps (co-authored with

TWAS Prize.[3]

Biography

Born on November 17, 1946, in Guapé, Minas Gerais, Welington studied electrical engineering at the Federal University of Minas Gerais (1969). He adopted mathematics after attending a course in the researcher of the Elon Lages Lima Institute in a colloquium in Poços de Caldas, Minas Gerais. Invited by Elon to study at Instituto Nacional de Matemática Pura e Aplicada he moved to Rio de Janeiro with his wife Gilza in 1970, with Jacob Palis his advisor, where Welington completed his doctorate in two years, with a thesis published in the prestigious Inventiones Mathematicae in 1972. He did his post-doctorate in mathematics at the University of California, Berkeley in 1972. He returned two years later to Brazil to make a career as a researcher at IMPA, where he stayed ever since.[4]

Appreciated by different generations of mathematicians, Welington was known and respected for his academic rigor and scientific productivity. Besides mathematics, he was passionate about sailing. On 1987

Fields medalists
and many friends of IMPA.

He died on December 21, 2016, at age 70, of complications of a

heart attack.[6]
