On Rational Functions Sharing the Measure of Maximal Entropy

Research output: Contribution to journalArticlepeer-review


We show that describing rational functions f1, f2, ⋯ , fn sharing the measure of maximal entropy reduces to describing solutions of the functional equation A∘ X1= A∘ X2= ⋯ = A∘ Xn in rational functions. We also provide some results about solutions of this equation.
