... function, and the former is sharp in the sense that n log n is the true order of magnitude of the size of the largest dissociated subset of the set {0, 1} n . At the same time, the bound of Theorem ... every element of M, is a linear combination of the elements of Λ with the coefficients in {−1, 0, 1}. Hence, every subset sum of M is a linear combinatio...

... α(j) = 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 ... condition for the boundedness of all solutions of (1.1) and the scalar case of (1.1), respectively. The next result provides a sufficient condition for the boundedness of...
