Auteur: Mauricio Matos Peixoto

About the Editors: Maurício Peixoto, in1953, together with Leopoldo Nachbin, helped to found IMPA (Instituto Nacional de Matemática Pura e Aplicada), to which has been associated ever since and is a Emeritus Researcher at the present; Peixoto’s Theorem.is a key stone in mathematics and its extensions form a central area of research in dynamical systems. Peixoto introduced the concept of focal decomposition in dynamical systems. Awards and Honors 1969 Moinho Santista Prize for Mathematics and in 1987 received the Third World Academy of Science Award in Mathematics; 1975-1977 President of the Brazilian Mathematical Society; 1979-1980 President of the National Research Council; 1981-1991 President of the Brazilian Academy of Sciences; David Rand is Professor of Mathematics and is the co-director of the Systems Biology Centre, at University of Warwick. David Rand has made lasting contributions to pure and applied dynamical systems, and also to game theory, economics, theoretical physics, fluid dynamics, ecology and epidemiology, immunology and circadian rhythms. Rand published a dynamical game based on Cournot duopoly and showed that under rather natural conditions this game would have chaotic trajectories. His most recent work is on the interface between mathematics and systems biology. Awards and Honors 1986 Whitehead Prize of the London Mathematical Society. 1988 Wolfson Research Award. 1988 Founding editor of Nonlinearity 2004 Fellow, Institute of Mathematics and Its Applications (by invitation) 2005 Britten Lecturer. Mc Master University 2006 EPSRC Senior Research Fellowship Alberto A. Pinto is Professor of Mathematics at University of Porto and, previously, was Professor of Mathematics at University of Minho. Edson de Faria, Welington de Melo and Alberto A. Pinto have developed a theory in the global hyperbolicity of renormalization for smooth unimodal mappings that is published in Annals of Mathematics Alberto A. Pinto, David Randand Dennis Sullivan have developed an extensive theory characterizing the flexibility and rigidity of one and two dimensional hyperbolic dynamical systems and constructed Teichmuller spaces for them, in particular, for their conjugacy classes. This work has appeared in a number of papers and has been collected into a monograph that was published by Springer in 2008. Aragão de Carvalho, Diogo Pinheiro, Alberto A. Pinto and Maurício Peixoto are working in the semiclassical quantization of the pendulum equation using renormalization methods. Awards and Honors 1984- Augusto Martins prize at University of Porto 2007-Espinho town’s golden medal
