Abstract
Conditional summable hypotheses are given to obtain asymptotic summati on of some 2 x 2 difference systems. We obtain asymptotic formulae of the solutions of a perturbed system, knowing the recessive and dominan t solutions of the unperturbed system. The Casoratian is generally non constant and nonconvergent and it appears in the asymptotic formulas.
