From forcing to satisfaction in Kripke models of intuitionistic predicate logic Maryam Abiri^{} 

Abstract: We answer a natural question concerning the relation between forcing and satisfaction in Kripke models of intuitionistic predicate logic. We define a class of formulas denoted by R∗, with the property that forcing of any R∗formula in a node of a Kripke model of intuitionistic predicate logic implies its satisfaction in the classical structure attached to that node. We also prove that any formula with this property is an R∗formula. Language: English
