isOrevkovClass1

object isOrevkovClass1

Checks whether a sequent is in (a minor extension of) Orevkov's class 1.

This is a Glivenko class, i.e., whenever this function returns true for a first-order formula, then that formula is provable in intuitionistic logic iff it is provable in classical logic.
