Abstract

If ff is a meromorphic function from the complex plane C{\mathbb C} to the extended complex plane C\overline{ {\mathbb C} }, for r>0r > 0 let n(r)n(r) be the maximum number of solutions in {z ⁣:zr}\{z\colon |z| \leq r \} of f(z)=af(z) = a for aCa \in \overline{ {\mathbb C} }, and let A(r,f)A(r,f) be the average number of such solutions. Using a technique introduced by Toppila, we exhibit a meromorphic function for which lim infrn(r)/A(r,f)1.07328\liminf_{r\to\infty} n(r)/A(r,f) \geq 1.07328.
