Entire solutions of higher order Briot-Bouquet equations
Abstract
For a meromorphic function f in the complex plane, we determine when f and f(k) are algebraically dependent. This happens precisely when f belongs to the class W of elliptic functions and their degenerates, or satisfies a linear differential equation f(k) + af + b = 0 with constant coefficients. The case of functions having a pole was settled previously. We complete the proof by treating entire solutions.

AB - For a meromorphic function f in the complex plane, we determine when f and f^(k) are algebraically dependent. This happens precisely when f belongs to the class W of elliptic functions and their degenerates, or satisfies a linear differential equation f^(k) + af + b = 0 with constant coefficients. The case of functions having a pole was settled previously. We complete the proof by treating entire solutions.
