- A analytic number theoretic question (or ?):
-
- Given a function with domain and target C excepted a finite number of points.
- It maps Q into Q (Q denotes the set of rational numbers) and
- it is meromorph on C (this implies uniquely extendable from Q to C).
-
- Must this function be representable as the quotient of two polynomies with
- integer coefficients or are there other functions left (present a counter-
- example, please) ?
