About
Palis's research interests were mainly dynamical systems and differential equations. Some themes are global stability and hyperbolicity, bifurcations, attractors and chaotic systems. He proposed the Palis' conjectures (which form the Palis' program), which influenced the development of the theory of dynamical systems, and also of its applications to other sciences. He was a world leader in chaos theory research. Palis was an influential figure in the development of mathematics in Brazil.

Jacob Palis was born in Uberaba, Minas Gerais. His father was a Lebanese immigrant, and his mother was of Syrian ancestry. The couple had eight children (five men and three women), and Jacob was the youngest. His father was a merchant, owner of a large store, and supported and funded the studies of his children. Palis said that he already enjoyed mathematics in his childhood.
At 16, Palis moved to Rio de Janeiro to study engineering at the University of Brazil – now UFRJ. He was approved in first place in the entrance exam, but was not old enough to enroll; he then had to take the university's entry exam again a year later, where he once again finished in first place. He graduated in 1962 with honours and received the award for the best student.
In 1964, he moved to the United States. In 1966, he obtained his master's degree in mathematics under the guidance of Stephen Smale at the University of California, Berkeley, and in 1968 his PhD, with the thesis On Morse-Smale Diffeomorphisms, again with Smale as advisor.
In 1968, he returned to Brazil and became a researcher at the Instituto Nacional de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro, Brazil.
Beginning in 1973 he held a permanent position as professor at IMPA, where he was director from 1993 until 2003. He was Secretary-General of the Third World Academy of Sciences from 2004 to 2006, and elected its president in 2006 and remained on position till December 2012. He was also president of the International Mathematical Union from 1999 to 2002. He was president of the Brazilian Academy of Sciences from 2007 to 2016. Palis advised more than forty PhD students so far from more than ten countries, including Artur Oscar Lopes, Ricardo Mañé, Welington de Melo, Carlos Gustavo Moreira, Enrique Pujals and Marcelo Viana.
Palis died at a hospital in Rio de Janeiro, on 7 May 2025, at the age of 85. He had been hospitalized since March.
