On Equivalent Transformations of Infinitary Formulas under the
... (a) if a formula F is provable in the basic system then H ∪ {F } has the same stable models as H; (b) if F is equivalent to G in the basic system then H ∪ {F } and H ∪ {G} have the same stable models. Lemma 1. For any formula F and interpretation I, if I does not satisfy F then F I ⇒ ⊥ is a theorem ...
