摘要
P-集合是由内P-集合XF与外P-集合XF构成的集合对,P-集合副集的(σ,τ)-生成是由内副集的σ-生成Aσ(XF)与外副集的τ-生成Aτ(XF)构成的集合对。本文在P-集合与P-集合副集的(σ,τ)-生成的基础上,给出P-集合的(σ,τ)-扩展模型,得到P-集合与它的(σ,τ)-扩展的关系定理,讨论了P-集合的(σ,τ)-扩展性质。P-集合的(σ,τ)-扩展模型拓宽了P-集合的研究范围。
P-sets( packet sets) is a set pair composed of internal P-set XF and outer P-set XF , while the (σ,τ)-generation of assistant sets of P-sets is also a set pair composed ofσ-generation of internal assistant set Aσ(XF) and τ-generation of outer assistant set Aτ( XF ) .Based on the above knowledge, (σ,τ)-expansion model of P-sets is proposed.The rela-tionship theorem between P-sets and its (σ,τ)-expansion is presented.A series of propoties about the (σ,τ)-expansion of P-sets are discussed.(σ,τ)-expansion model of P-sets expands the research field of P-sets.
