Inverse P-sets
Shi Kai-quan · Journal of Shandong University · 2012
Using P-sets(packet sets),inverse P-sets(inverse packet sets) and its structure are presented,which is briefly expressed as P-1-sets.P-1-sets is the dual form of P-sets.P-1-sets is a set pair composed of internal inverse P-set F and outer inverse P-set,or(F,) is P-1-sets,and P-1-sets has the dynamic characteristic.The separation theorem and dynamic equivalence class characteristic of P-1-sets and the application of P-1-sets are given in the dynamic information system.
