The question is studied of the possibility of extending the intuitionistic propositional calculus by adding single-valued one-place operations which are not expressible in terms of conjunction, disjunction, implication, or negation. There is constructed a system of correct calculi with new single-valued operations which is isomorphic to the family of proper extensions of the intuitionistic propositional calculus.
