摘要
本文利用变指标Hardy空间的原子分解,应用经典不等式和变指数的性质,证明了带变量核的变指数分数次积分算子从变指标Hardy空间到变指标Lebesgue空间的有界性.
In this paper, by the atomic decomposition of the Hardy spaces with variable exponents, using the estimates of classical inequality and the properties of the variable exponents, we proved that the fractional integral operators with variable kernels associated to variable exponents are bounded from the Hardy spaces to Lebesgue spaces with variable exponents.
