Abstract
In this paper, we prove some new characterizations of two weighted functions u and v in norm inequalities of Hardy’s type, in the context of dynamic inequalities on time scales \({\mathbb {T}}\). These norm inequalities studied the boundedness of the operator of Hardy’s type between the weighted spaces \( L_{v}^{p}({\mathbb {T}})\) and \(L_{u}^{q}(\mathbb {T)}\). The paper covers the different cases when \(1<p\le q<\infty \) and when \(1<q<p<\infty \). As special cases, when \(\mathbb {T=R}\), we obtain the corresponding previously known results from the literature, while for \(\mathbb {T=N}\) we obtain some discrete results which are essentially new. In seeking applications, we will establish some non-oscillation results for second-order half-linear dynamic equations on time scales.
