N2 - The relations between the classes of positive and strongly positive arithmetical sets are investigated. Some simplified form for the logical representation of the class of positive sets is obtained. It is proved that the logical representation of the class of positive sets is obtained when the list of operations &,∨ in the definition of the class of strongly positive sets is replaced by the list ∃,&,∨ .
