Abstract:
Various variants of the notion of the $V$-realizability for predicate formulas are defined, where indexes of functions in the set $V$ are used for interpreting the implication and the universal quantifier. It is proved that Markov's Principle is weakly $V$-realizable, not uniformly $V$-realizable, and uniformly $V$-realizable in any $V$-enumerable domain $M \subseteq \mathbb {N}$.
