By overspill, the almost-periodicity up to iotas implies that there exists some ω ∈ ∗N \ N such that for h ∈ {1, α} (∀x ∈ ∗R)(|x| ≤ R =⇒ |f (x + h) − f (x)| ≤ ρω ).
Group invariant Colombeau generalized functions
If k , l are moderate and k − lα ≈ 0, we have in particular (as R can be taken arbitrarily large) that k − lα is an almost-period up to iotas for f on the whole of ns(∗R).

So for each n ∈ N, f has almost-periods up to iotas hn with ρnM < hn < 2ρn .

The simplest way to define Iota is in terms of Church’s λ−calculus: the universal basis {S = λxyz .xz (yz ), K = λxy .x} suffices to produce every lambda term, but for universality it is not necessary to have two combinators.
