Mixed Bourgain-Morrey spaces and their applications to boundedness of operators

Tengfei Bai, Pengfei Guo, Jingshi Xu

We introduce the mixed Bourgain-Morrey spaces and obtain their preduals. The boundedness of Hardy-Littlewood maximal operator, iterated maximal operator, fractional integral operat…

The Weighted Grand Herz-Morrey-Lizorkin-Triebel Spaces with Variable Exponents

Shengrong Wang, Pengfei Guo, Jingshi Xu

Let a vector-valued sublinear operator satisfy the size condition and be bounded on weighted Lebesgue spaces with variable exponent. Then we obtain its boundedness on weighted gran…

Precompact Sets in Matrix Weighted Lebesgue Spaces with Variable Exponent

Shengrong Wang, Pengfei Guo, Jingshi Xu

In this paper, we first give a sufficiently condition for precompactness in the matrix-weighted Lebesgue spaces with variable exponent by translation operator. Then we obtain a cri…
