An Induction Principle and Pigeonhole Principles for K-Finite Sets
Andreas R. Blass · arXiv (Cornell University) · 1994
We establish a course-of-values induction principle for K-finite sets in intuitionistic type theory. Using this principle, we prove a pigeonhole principle conjectured by Benabou and Loiseau. We also comment on some variants of this pigeonhole principle.
