Nest Ordinals with Functions
This will enhance the ordinals expansion greatly as they are currenyly expanded based on multiplication and exponentiation only. Part I: Up Arrow & Ordinals for Sequential Functions The up arrow notation can be added to ordinals in the form of f α↑ k β (n), where f is FGH fundamental sequence function, where k and n are positive integers; α and β are ordinals. Similar to expansion of ordinals, α↑ k β is right associative (expanding from right to left). f α↑ k β+1 (n) = f ...(((α↑ k β)↑ k β)↑ k β)... (n) (with n copies of ↑ k 's). All other rules shall follow the rules of Up Arrow and the rules of ordinal expansion. Examples: f ω↑ω (2) = f ω↑2 (2) = f ω 2 (2) = ... f ω↑↑ω (2) = f ω↑↑2 (2) = f ω ω (2) = f ω 2 (2) = ... f ω↑↑(ω+1) (2) = f ((ω↑↑ω)↑↑ω) (2) = f ((ω↑↑ω)↑↑2) ((2) = ... f ε 0 ↑↑↑ε 0 (2) = f ε 0 ↑↑↑ ω ω (2) = f ε 0 ↑↑↑ ω 2 (2) = f ε 0 ↑↑↑ ω2 (2) = f ε 0 ↑↑↑ω+ω (2) = f ε 0 ↑↑↑ω+2 (2) = f ((ε 0 ↑↑↑ω+1)↑↑↑ω+1) (2) = f ((...
