How would I design a non-trivial algebraic function of degree 4 containing a branch at the origin with the (finite) power expansion:
##w(z)=1+0.5 z-1/4 z^{1/2}+3/4 z^{1/4}##?
having the form
## f(z,w)=a_0+a_1 w+a_2 w^2+a_3 w^3+a_4 w^4=0##
with the ##a_i ## ( preferably not fractional) polynomials? And if that is possible, can I design any function ##w(z)## with a finite power expansion with ##f## of any degree?
I don't know.
