Title: Entire functions with small orbits
Abstract: Erdos proved that the existence of an uncountable family of entire functions that take countably many values at each complex number is equivalent to CH. He asked what happens if we replace uncountable by continuum and countable by less than continuum? We show that in this case the answer is independent of ZFC plus not CH. Joint work with Shelah.
