Since the Schroeder function doesn't exist when the multiplier at the fixed point is 1, or a rational root of 1, then one can use Ecalle's solution for the Abel function.
Hi
I want to use fatou.gp.ecalle() evaluate Shell-Thron-region rational base, but my series input isn't work. can you give me some code for examples?
And...I want to evaluate derivative for sexp/slog/pent/sroot, Can I just use deriv(sexptaylor()), deriv(slogtaylor()), deriv(kecalle), deriv(pentaylor()), deriv(gm)?
I see the ihex_deriv() you use are not simple.
ecalleu(z1) /* [abel_function,abel_function_derivative]; [44.892671576806680805639501168174, */
ecalleu(z2) /* [abel_function,abel_function_derivative]; [45.892671576806680693723673529703, */

1.Is the sexpeta() merged upper & low superfunction?
2.Can the cheta/incheta/sexpeta/slogeta normal work when base isn't eta?
