Abstract

In article the class of the whole functions which grow not quicker exp{γ|z|6/5(ln|z|)–1} is studied and accept together with the first derivatives the whole rational values in points of positive part of a two-dimensional lattice of a general view. It is shown that any such function is or a polynomial with rational coefficients, or is presented in the polynomial form with rational coefficients from function ez/q at some natural q.
