Abstract: |
This article investigates the relation between solutions of nonhomogeneous differential equation and small functions. By using theory of complex analysis, we obtain some precise estimate between the solutions and the small functions. It shows that this relation is influenced by the growth of the solutions. |
Key words: nonhomogeneous differential equation exponent of convergence small function |
