Abstract: The concepts of inner and outer P-dual information and P-dual attribute information are defined by using dynamic characteristic of P-sets. On the basis of these concepts, dependence and dependence degree, dependence coefficient of P-information and P-dual attribute information are given. Inner and outer P-attribute information dependence theorems, P-dual information acquirement-discovery theorem and inner hidden theorem are discussed. Two dependence-acquirement criterions are gotten on P-dual information. In the end, the application of P-dual information is presented.

Key words: P-dual information, dependence degree, dependence-acquirement, hidden criterion
