摘要：

We study weighted modular inequalities with variable exponents for the Hardy operator restricted to non-increasing functions. We show that the exponents p(.) for which these modular inequalities hold must have a constant oscillation at zero, which implies that these exponents are either constant or extremely oscillating near the origin. Similarly to the constant case, we introduce the class of weights B-p(.), and prove some of the classical properties in this context. (C) 2008 Elsevier Inc. All rights reserved.
