Let f(z) be an analytic function with a riemann surface that has branches.
Let RB be shorthand for going from one specific Riemann Branch to another specific one.
Then the equation that holds locally or globally :
RB ( f(z) ) = f( p(z) )
with p(z) a degree 1 or 2 polynomial.
fascinates me.
For instance f(2z+1) is another branch of f(z).
That is fascinating.
But how to solve such a thing ?
in particular
RB ( f(z) ) = f(z + C)
This relates to tetration and dynamics.
Not sure if its in the books.
Btw do not confuse with a simple invariant :
p (f(z)) is another branch of f(z).
which is different !!
