Abstract
- In this paper we study the effect of linear differential operators coming from the Laguerre-Polya class that act on functions in the extended Laguerre-Polya class with zeros in a horizontal strip in the complex plane. These operator decrease the size of the strip containing the zeros.<br />Comment: 17 pages, corrected several typos, added a citation. appears in Math. Anal. Appl. (2015)
