Two‐dimensional solvable system of difference equations with periodic coefficients

Mathematical Methods in the Applied Sciences, 2019
We show that the following two‐dimensional system of difference equations: urn:x-wiley:mma:media:mma5780:mma5780-math-0001 where , , , and are periodic sequences, is solvable, considerably extending some results in the literature. In the case when all these four sequences are periodic with period 2 or with period 3, we present closed‐form ...
