Abstract: If is continuous and increasing then a meromorphic function *f* on is said to be of finite -type if there are positive constants *s, A, B* and *R* such that for all where is the characteristic of *f*. It is shown that if is bounded for *r* sufficiently large and , then every meromorphic function of finite -type is the quotient of two entire functions of finite -type.

This theorem is the result of a careful and detailed analysis of the relation between the growth of a function and the growth of its divisors. The central fact developed in this connection is: A nonnegative divisor on with is the divisor of an entire function of finite -type if and only if there are positive constants *A, B* and *R* such that

*p*. Here represents the lifting of the divisor to the plane via the map and is the valence function of that divisor.

Analogous facts for functions of zero -type are also presented.
