摘要：
In this article, we study the exponent of convergence of f((i)) - phi where f not equivalent to 0 is a solution of linear differential equations with analytic and meromorphic coefficients in the unit disc and phi is a small function of f. From this results we deduce the fixed points of f((i)) by taking phi(z) = z. We will see the similarities and differences between the complex plane and the unit disc.
