Abstract
Using Nevanlinna theory of the value distribution of meromorphic functions,the problem of the growth of solutions of f″+ A(z)f′ + B(z)f = 0 is investigated,where A(z)is a nontrivial solution of the equation w + P(z)w = 0,P(z) is a polynomial of degree n.And under the assumption of certain proper conditions of B(z),we prove a result which every nontrivial solutions f(z) of the equation is of infinite order and improve some results in previous references.
