We’re doing this again!
I’m skipping Fish Number 2 because I’m really confused by it. I’ll do it next time.
Remember Fish Number 1? With the S and SS map? We have to define a new map. The s(n) MAP!
This is mainly just copied from the Googology Wikia.
Define s(n) map as:
- s(1)f := g; g(x) = fx(x)
- s(n)f := g; g(x) = [s(n-1)x]f(x) (if n > 1)
where s(n) is a functional, and the rate of growth in the fast-growing hierarchy is s(x)f(x) ≈ fω^ω(x).
Define ss(n) map to be:
- ss(1)f := g; g(x) = s(x)f(x)
- ss(n)f := g; g(x) = [ss(n-1)x]f(x) (if n > 1)
and its growth rate is:
- ss(1)f(x) = s(x)f(x) ≈ fω^ω(x)
- ss(n)f(x) ≈ fω^(ω+n+1)(x)
Huge.
Definition and the growth rate of Fish function 3:
- F3(x) := ss(2)63f; f(x) = x + 1
- F3(x) ≈ f(ω^(ω+1)) * 63
Fish Number 3 is:
F3 := F363(3) ≈ fωω+1 * 63 + 1(63)
