Abstract: |
In this paper, we study the growth of meromorphic solutions of a class of higher order linear difference equations. By using the Phragmén-Lindelöf indicator functions, we obtain an estimation of lower bound of the growth of meromorphic solutions of the difference equations if it has at least two dominating coefficients with same type, which improves the previous results. |
Key words: order of growth linear difference equation dominating coefficients indicator function |
