Jacob Palis

Jacob Palis, Jr. (b. 15 March 1940 in Uberaba, Brazil) is a Brazilian mathematician of international recognition. Since 1973 he has held a permanent position as professor at Instituto Nacional de Matemática Pura e Aplicada in Rio de Janeiro, Brazil. He was director of the same institute 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 [http://www.ictp.trieste.it/~twas/publ/2006-09-04_Palis.html] .

He studied under Stephen Smale at University of California, Berkeley, and his 1968 thesis was entitled "On Morse-Smale Diffeomorphisms". Palis himself has advised more than forty Ph.D. students so far from more than ten countries.

Palis has received numerous medals and decoration. He is a foreign member of several academies of sciences, including the United States National Academy of Sciences and the French Academy of Sciences. In 2005 Palis was selected a member of the Legion of Honor.

His Erdös number is 3.

Research interests

Mainly dynamical systems and differential equations. Some themes are: Global stability and hyperbolicity, bifurcations, attractors and chaotic systems.
