摘要
本文给出了 \(H_{\omega }^{p(\cdot )}(\mathbb {R}^{n})\) 的分子重构定理。作为这一结果以及在 Ho (Tohoku Math J 69 (3), 383-413, 2017) 中发展的原子分解的应用,我们证明经典奇异积分可以扩展到 \(H_{\omega }^{p(\cdot )}(\mathbb {R}^{n})\ 上的有界算子。)我们还证明,对于某些指数(q(\cdot ))和某些权重(\omega }),里兹势(I_{\alpha }),随着(0< \alpha <;n\), can be extended to a bounded operator from \(H^{p(\cdot )}_{\omega }(\mathbb {R}^{n})\) into \(H^{q(\cdot )}_{\omega }(\mathbb {R}^{n})\), for\(\frac{1}{p(\cdot )}:= \frac{1}{q(\cdot )} + \frac{α }{n}\).
A molecular reconstruction theorem for $$H^{p(\cdot )}_{\omega }(\mathbb {R}^{n})$$
In this article we give a molecular reconstruction theorem for \(H_{\omega }^{p(\cdot )}(\mathbb {R}^{n})\). As an application of this result and the atomic decomposition developed in Ho (Tohoku Math J 69 (3), 383–413, 2017) we show that classical singular integrals can be extended to bounded operators on \(H_{\omega }^{p(\cdot )}(\mathbb {R}^{n})\). We also prove, for certain exponents \(q(\cdot )\) and certain weights \(\omega \), that the Riesz potential \(I_{\alpha }\), with \(0< \alpha < n\), can be extended to a bounded operator from \(H^{p(\cdot )}_{\omega }(\mathbb {R}^{n})\) into \(H^{q(\cdot )}_{\omega }(\mathbb {R}^{n})\), for \(\frac{1}{p(\cdot )}:= \frac{1}{q(\cdot )} + \frac{\alpha }{n}\).
