AN EVEN ENTIRE FUNCTION OF ORDER ONE IS A SPECIAL SOLUTION FOR A CLASSICAL WAVE EQUATION IN ONE-DIMENSIONAL SPACE

ABSTRACT
In this article we consider an even entire function of order one as the solution of the classical wave equation in one-dimensional space. We suggest a conjecture that this function has only purely real zeros in the entire complex plane. This is given as a new prospective on a nice connection with number theory and wave equation.
