In this regard, the newness of this work is the study of a new characters formula, recently published by Schützer [Sch12], and this based in one combinatory given only in terms of not simple positive roots of the Lie algebra. The main results of this dissertation are reviewed and clarified. / O objetivo deste trabalho é descrever formalmente as representações irredutíveis das álgebras de Lie semissimples g de dimensão finita sobre um corpo algebricamente fechado de característica zero, como também obter algumas fórmulas de multiplicidades que permitem calcular a dimensão dos espaços de peso da representação e também a quantidade de pesos. Nesse sentido, a novidade deste trabalho é o estudo de uma nova fórmula de Caracteres, recentemente encontrada por Schützer [Sch12], e que se baseia em uma combinatória dada apenas em termos das raízes positivas não simples da álgebra de Lie. Os principais resultados desse artigo são revistos e clarificados.
