Abstract:

Based on internal P-set,  the concepts and structures of assistant set, σ-assistant set and function internal P(σ)-set related to function internal P-set were obtained, and then  the relationship between function internal P-set and function internal P(σ)-set was discussed. Moreover, we derived the theorems about dynamic change depending on attributes and threshold value. Because of  the law characteristics of function internal P(σ)-set, its dynamic change was also researched and identification theorems about law change were found.

Key words: function P-set, σ-assistant set of function P-set, function internal P(σ)-set, dynamic characteristics 
