However, they encode recursion using a fixed point com-binator and use transfinite size arithmetic, both of which we avoid as we explained in the introduction.

Induction is a method of proof based on a inductive set, a well-order, or a well-founded relation. I Most important proof technique used in computing. I The proof method is specified by an induction principle. I Induction is especially useful for proving properties about recursively defined functions.
