Lecture 18: Completeness of Labeled Deduction
In this lecture we prove completeness of
labeled deduction for intuitionistic propositional logic. The critical
idea is to identify monotone sequents where labels on the right
hand side are all equal, and every label on the left is a prefix of the
label on the right. The completeness proof is more difficult and
we will not cover it in this course.
