Let R = (ri' r 2 , ... ) be a finite or infinite (strictly increasing) sequence of positive integers and let (Wi' W2 , ••• ) be a sequence of wedges in the complex plane. Consider the following problem: Characterize those complex numbers c for which (Ll) for k = 1,2, .... It is shown in [1 J and [4J that, under certain assumptions on the wedges and on the density of the sequence R, the set of a...
