Inverse P(ρ(σ),η(τ))-sets and their algebra feature
Zhang Yue-yu · Computer Engineering and Applications Journal · 2014
Based on the inverse P-sets( XˉF,XˉFˉ), the concept and structure of inverse P( ρ(σ), η(τ))-sets with random translation characteristics are proposed. The relationship between inverse P(ρ(σ),η(τ))-sets and inverse P-sets is discussed, which shows P( ρ(σ), η(τ))-sets are the general forming of inverse P-sets, while inverse P-sets are a special case of P( ρ(σ),η(τ))-sets.Four operations including intersection, union set, complementary set and difference set are presented. Furthermore the algebra feature about inverse P( ρ(σ),η(τ))-sets is given.
