Abstract

Definem-se os aproximantes Padés-Hermite e se mostra como construí-los. Faz-se uma aplicação na análise de um sistema de esferas duras, com o objetivo de encontrar um equação de estado termodinâmica, com base na expansão virial de Ursell-Mayer para a pressão. Procura-se obter informações sobre possíveis ocorrências de transições de fase termodinâmicas no sistema.
