Abstract:

P-sets (packet sets) is a pair of sets composed of internal P-set (internal packet set) and outer P-set (outer packet set), which has dynamic characteristics. Based on Psets, assistant sets of P-sets and its (σ,τ)-generation are defined. Furthermore, the relationship between assistant sets of P-sets are discussed, the generation theorem and unidentification theorem related to assistant sets are obtained.

Key words: P-sets; assistant sets of P-sets; (σ,τ)-generation of assistant sets; generation theorem; relationship theorem
