| Abstract: | In this paper, the zeros of solutions of periodic second order linear differential equation $y'+Ay=0$, where $A(z)=B(e^z)$, $B(\zeta)=g(\zeta)+\sum_{j=1}^pb_{-j}\zeta^{-j}$, $g(\zeta)$ is a transcendental entire function of lower order no more than $1/2$, and $p$ is an odd positive integer, are studied. It is shown that every non-trivial solution of above equation satisfies the exponent of convergence of zeros equals to infinity. |
