Talk:Bell series

From Wikipedia, the free encyclopedia

The uniqueness theorem is a triviality. I would like to see some interesting applications of Bell series. They seem to be pretty boring objects. Why ? If your arithmetic function is integer valued (and most "interesting" arithmetic functions have integer values), then its Bell series must be either rational or have a natural boundary at its radius of convergence (this is a fairly deep theorem, conjectured by Polya, and proved by Carleson I think) ... In other words the Bell series is either "too trivial" to be studied, or in the other direction, too complicated to get anything useful out of it . This is at least how I see it. Reactions ?
