Iteration basics

[bo198214]

\( \phi(f^{\circ I}(x))=\phi(x)+I \).

If we turn it upside down, we can may be use the result of t iterations of a function to define what COUNTING with t (e.g. t=I) means.

Ivars, we do exactly that! How do you think we compute \( b[4](I*t) \)?
I wrote it already

The equation \( f^{\circ n}(x)=\phi^{\circ-1}(\phi(x)+n) \) is of course easily applicable to complex \( n \) nothing needs to be changed just keep the law for complex \( n \) too. E.g.
\( f^{\circ I}(z)=\phi^{\circ -1}(\phi(z)+I) \).

in this previous post

But btw this give no clue about what x[I]y is.
