Abstract:

Based on P-sets, the concept and structure of P-relation are generated, and operation with respect to it and its value metric are given. Also, the contraction theorem of degree discrete interval of P-relation as well as generation-recovery theorem of P-relation are proposed. Finally, application of P-relation in information identification is given.

Key words:  P-sets; P-relation; discrete interval of the degree; commutative semigroups; information identification
