Abstract: We consider the problem of satisfiability for systems of countable-valued functional equations, containing ternary discriminator function $p$. We prove that this problem is $m$-complete in the class $\Pi_1$ of Kleene–Mostovsky's hierarchy.
Keywords: functional equations, countable-valued logic, problem of satisfiability.
