Lecture 4: Type Preservation for Mini-MLWe continue our discussion of the type system for Mini-ML from the previous lecture and finish the type preservation theorem. One important lemma in this proof is a substitution lemma which we first generalize before we can prove it by induction. Suggested Reading Materials:Frank Pfenning. Computation and Deduction, Chapter 2.6 - End of Chapter 2.
