Recursive types in polymorphic lambda calculus
Recursive types in polymorphic lambda calculus
There is a fairly standard encoding of recursive types
into polymorphic lambda calculus, given by
rec X.F[X] = all X.(F[X] -> X) -> X
where F[X] is a type in which the type variable X appears only
covariantly.

Complex number- Locus and finding the greatest, lowest of argument
I have no idea what a locus means so
The complex number u is given by u=(7+4i)/(3-2i). In the form x+yi, x=i, y=2

Principle of Mathematical Induction
From ProofWiki
Let $P \left({n}\right)$ be a propositional function depending on $n \in \N$.
If the following statements hold:
$(1): \quad P \left({n_0}\right)$ is true for some $n_0 \in \N$ (where $n_0$ is often, but not always, zero or one)
