WebInductive Families¶ We are almost done describing the full range of inductive definitions accepted by Lean. So far, you have seen that Lean allows you to introduce inductive … Webinductive families [10], a mechanism that can be used to de ne basic types like nat and bool, and common type-forming operations, like Cartesian products, lists, -types, and so on. Each inductive family declaration generates a recursor (also known as the eliminator). Lean’s kernel can be instantiated in di erent ways.

As we have marked expP as a family of proofs, we cannot deconstruct our expressions in the usual programmatic ways, which makes them almost useless for the usual purposes. Impredicative quantification is much more useful in defining inductive families that we really think of as judgments. fireworks dc today

"WebI am totally lost on how to approach this problem since the eliminator seems to be able to provide just function defined on the whole family List′A(n) and not on the sub-family List′A(s(n)). The typical trick in this situation is to pick a C such that you can pretend you are defining a function on the whole family when, in fact, you're only focusing on the sub … " - Inductive family

If types are viewed as like sets, as was traditionally the case in type theory, then there are no such operations, and hence we expect there to be no elements in an inductive type other than those resulting from its …
