Abstract
We prove the existence of a function @f which is holomorphic exactly in the unit disk D and has universal translates with respect to a prescribed closed set [email protected][email protected]?D and satisfies @[email protected]?C^~(@?D\E). If Q is a subsequence of N"0 with upper density d(Q)=1 then the function @f can be constructed such that in [email protected] (z)[email protected]?n=0~a"nz^nwitha"[email protected]?Q.
