Welington Celso de Melo (born November 17, 1946 in Guapé , Minas Gerais , † December 21, 2016 in Rio de Janeiro ) was a Brazilian mathematician who dealt with dynamic systems (especially one-dimensional dynamic systems).

De Melo made 1969 his degree in electrical engineering at the State University of Minas Gerais and in 1972 at IMPA at Jacob Palis PhD (Structural Stability of diffeomorphisms of two manifolds). He was a post-doctoral student at the University of Warwick . In 1974 he became an assistant professor and in 1980 he was given a full professorship at IMPA.

He was visiting scholar at the University of California, Berkeley , at the ICTP in Trieste, at the University of Paris-Süd , at IHES , the University of Lille, the University of Lyon, the City University of New York, the State University of New York at Stony Brook , at the Royal Stockholm Technical University, the University of Porto, the Lorentz Center in Leiden and the University of Delft.

With Marco Martens and Sebastian van Strien in 1992 he gave a complete description of the topological behavior of one-dimensional real dynamic systems. They showed that the Julia-Fatou-Sullivan theory from holomorphic dynamics can also be used there.

In 1991 he became a member of the Brazilian Academy of Sciences. In 1998 he was invited speaker at the International Congress of Mathematicians in Berlin (Rigidity and Renormalization in One Dimensional Dynamical Systems). In 2002 he received the Grã Cruz da Ordem Nacional do Merito Científico from the Brazilian President after he had become the order's commander in 1996. In 2004 he became a member of the Third World Academy of Sciences, whose mathematics prize he received in 2003.

Artur Ávila is one of his PhD students .
