Complex flows, escape to infinity and a question of Rubel

Complex flows, escape to infinity and a question of Rubel

Let \(f\) be a transcendental entire function. It was shown in a previous paper (2017) that the holomorphic flow \(\dot z = f(z)\) always has infinitely many trajectories tending to infinity in finite time. It will be proved here that such trajectories are in a certain sense rare, although an …
