On Maximum Modulus Points and the Zero Set for an Entire Function of either Zero or Infinite Order

On Maximum Modulus Points and the Zero Set for an Entire Function of either Zero or Infinite Order A maximum modulus point of an entire function f is a point w such that ¦f(w)¦ = max¦f(z)¦: ¦z¦ = ¦w¦. Denote by R(w,f) the distance between a maximum modulus point w and the zero set of f. In 1938, A. J. Macintyre obtained lower asymptotic estimates for R(w, f) as ¦w¦ →∞ valid outside of an exceptional set. The problem of asymptotic estimates valid for all sufficiently large ¦w¦ was studied by I. V. Ostrovskii and the author for functions of finite positive order. In this paper, we study this problem for functions of either zero or infinite order. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Computational Methods and Function Theory Springer Journals

Abstract

A maximum modulus point of an entire function f is a point w such that ¦f(w)¦ = max¦f(z)¦: ¦z¦ = ¦w¦. Denote by R(w,f) the distance between a maximum modulus point w and the zero set of f. In 1938, A. J. Macintyre obtained lower asymptotic estimates for R(w, f) as ¦w¦ →∞ valid outside of an exceptional set. The problem of asymptotic estimates valid for all sufficiently large ¦w¦ was studied by I. V. Ostrovskii and the author for functions of finite positive order. In this paper, we study this problem for functions of either zero or infinite order.
