“…Recently, there has been an increasing interest in the study on the properties of meromorphic solutions of complex difference equations from the viewpoint of difference analogues of Nevanlinna theory (see [4,6,8]) and among those many good results are obtained for the case of complex linear difference equations (see [4,5,6,11,12,14,16,19,20]). For the case of complex linear differential-difference equations see [1,2,3,13,15,21].…”
