In this work we make a detailed study of poset spaces, hierarchy of I -weights and I -distribution of P P weights, emphasizing the non-degenerate poset codes. We verify the duality relation between the hierarchy weights of poset code and its dual. In the sequel two new parameters are defined to a class of poset codes non-degenerate with dual code is too non-degenerate in the environment. As a result enunciated in the Minimality Theorem, the Variance Theorem and the Minimality Identity in the poset spaces. / Uma generalização da métrica de Hamming é a métrica poset. Faremos um estudo detalhado dos espaços poset, hierarquia de I-pesos e a I-distribuição de pesos, dando ênfase aos códigos poset não degenerados. Verificamos a relação de dualidade poset entre as hierarquias de um código e seu dual. Definimos dois novos parâmetros para a classe de códigos dualmente não degenerados no ambiente poset. Como consequência, enunciamos e mostramos o Teorema da Minimalidade, o Teorema da e Variância e a Identidade de Minimalidades no espaço poset.
