One property of zero set of function invertible in the sense of Ehrenpreis in the Schwartz algebra

Abstract

We consider those elements of the Schwartz algebra of entire functions which are Fourier-Laplace transforms of invertible distributions with compact supports on the real line. These functions are called invertible in the sense of Ehrenpreis. The presented result concerns with the properties of zero subsets of invertible in the sense of Ehrenpreis function f . Namely, we establish some properties of the zero subset formed by zeros of f laying not far from the real axis.
