TY - JOUR TI - An even entire function of order one is a special solution for a classical wave equation in one-dimensional space AU - Yang Xiao-Jun AU - Alsolami Abdulrahman Ali AU - Ali Ahmed Refaie JN - Thermal Science PY - 2023 VL - 27 IS - 1 SP - 491 EP - 495 PT - Article AB - 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.
