Ivars Wrote:\( f(x) = \ln(x) \text{ if } x>0 \)
\( f(x) = \ln(-x) \text{ if }x<0 \)
As Henryk noted, this can be easier expressed as \( f(x)=\ln(|x|) \)

I wonder what the continuous iteration including negative of this function would mean?
\( f^{\circ t}(x) \) for real t ?
Would it mean that Integral over t from
Integral dt \( {f^{\circ t}(x)/t}= -\Omega \)?
Integral dt \( {f^{\circ t}(1/x)/t}= \Omega \)?
