KRIPKE MODELS FOR INTUITIONISTIC THEORIES WITH DECIDABLE ATOMIC FORMULASZoran Markovi\'cAbstract: Some intuitionistic theories, notably Heyting's Arithmetic, have decidable atomic formulas. We show that in Kripke models of such theories, classical structures at the nodes of a Kripke model satisfy a significant fragment of corresponding theories. In particular, all consequences which are in prenex normal form hold classically. Classification (MSC2000): 03B50, 03C40 Full text of the article:
