Title in Portuguese
Renormalização de aplicações unimodais com ordem crítica próxima a 2N
Keywords in Portuguese
Complex bounds
Renormalização
Unimodal
Abstract in Portuguese
Nós estudamos a dinâmica do operador de renormalização atuando no espaço de pares (?, t), onde ? é um difeomorfismo e t ? [0, 1], interpretados como aplicações unimodais ? o qt, onde qt(x) = -2t|x|? + 2t - 1. Estabelecemos cotas complexas a priori para pares suficientemente renormalizáveis com combinatória limitada e então a utilizamos para mostrar que quando o expoente crítico ? está próximo de um número par, o operador de renormalização tem um único ponto fixo, o qual é hiperbólico e possui uma variedade estável de codimensão um que contém todos os pares infinitamente renormalizáveis

Abstract in English
We study the dynamics of the renormalization operator acting on the space of pairs (?, t), where ? is a diffeomorphism and t ? [0, 1], interpretated as unimodal maps ? o qt, where qt(x) = -2t|x|? + 2t - 1. We prove the so called complex bounds for sufficiently renormalizable pairs with bounded combinatorics. This allows us to show that if the critical exponent ? is close to an even number then the renormalization operator has a unique fixed point. Furthermore this fixed point is hyperbolic and its codimension one stable manifold contains all infinitely renormalizable pairs
