Abstract:In this paper,we will investigate the relation between the order of E(z) and the order of meromorphic function A (z) , where E (z) = f1f2 andf1 , f2 are any two linearly independent solutions of the complex differential equationf″ + A(z)f = 0. With regard to the equationf(k) + Ak-1 (z)f(k-1) + … + A1(z)f' + A0(z)f = 0, we will investigate the relations among the orders of A0(z),A1(z), Ak-1 (z) when order and the exponent of convergence of zero -sequence of non-trivial solutions of the equation satisfy certain conditions.
Keywords:deficient value  order  exponent of convergence of zero-sequence
