Abstract
In this paper we discuses the periodic solutions of particular cases of the following general system of difference equations
where the initial conditions
,
,
,
,
,
are arbitrary nonzero real numbers and
,
,
,
= 1, 2, 3, 4,
= 1, 2, 3, 4, 5 are non-negative real numbers. The results obtained are new and contained as special cases some other results.
