... ⋂ bÎΓ X b . The proof of Theorem 3.1 is therefore complete. As a consequence of this theorem, we obtain the following common fixed point result. Theorem 3.2. Let X be a comple te lattice. Then, an ... (F b ) bÎΓ is decreasing . Theorem 3.1 implies that ⋂ bÎΓ F b is nonempty and is a complete su blattice of X. The proof of Theorem 3.2 is therefore complete. The commutativity...

... 0, 0 ≤ j ≤ n. Then the solution of (4.4) and (4.5) is bounded if and only if the condition (5.5) is satisfied. Proof. The proof is immediate consequence from proof of Theorem 4.3 with Remark 5.1. Remark ... proof. Theorem 3.1. Let (A) and (B) be satisfied and assume that the initial vector x 0 belongs to the set S. Then the solution x(n; x 0 ), n ≥ 0, of (1.1) and...
