Abstract:

The P-set is generalized from finite sets to arbitrary set. The dynamic σ-algebra of P-set and P-measure space are proposed according to the knowledge about measure theory based on the given measure space. The P-set based on the arbitrary ordinary sets is studied,which is provided reliable theory support for the information safety.

Key words:  ordinary set; P-set; measure; P-measure space
