Abstract

Some properties of the roots of theories, and the relationship between the sets D(@C) of all conclusions of two different theories in the classical propositional logic system, Lukasiewicz propositional logic system, and the R"0-propositional logic system are studied. It is proved that D(@C) is completely determined by its root whenever @C has a root, and the construction of the roots is given.
