A system of linear ordinary differential equations with exponential coefficients is considered; several theorems are presented concerning general solutions and their asymptotic forms for large values ...

Let w1 and w2 be two linearly independent solutions to w" + Aw = 0, where A is a transcendental entire function of order $\rho(A) < 1$. We show that the exponent of convergence λ(E) of the zeros of E ...
