Nesta tese, introduzimos o conceito de sequência convergente de permutações e provamos a existência de um objeto limite para tais sequências. Introduzimos ainda um novo modelo de permutação aleatória baseado em tais objetos e introduzimos um conceito novo de distância entre permutações. Provamos então que sequências de permutações aleatórias são convergentes e provamos a equivalência entre esta noção de convergência e convergência nesta nova distância. Obtemos ainda resultados de amostragem e quase-aleatoriedade para permutações. Provamos também uma caracterização para parâmetros testáveis de permutações.We introduce the concept of convergent sequence of permutations and we prove the existence of a limit object for these sequences. We also ...
