Abstract: By using Nevanlinna theory, we generalize a result given by Wittich to complex differential‐difference equations. The result obtained is that the differential‐difference equation in f which is of only one dominant term, has no admissible…

Abstract: We show that the following two‐dimensional system of difference equations: xn+1=anxn+bnyn,yn+1=cnxn+dnyn,n∈N0, where (an)n∈N0 , (bn)n∈N0 , (cn)n∈N0 , and (dn)n∈N0 are periodic sequences, is solvable, considerably extending some results in the literature. In the case…
