Equivalent norms and -transform of matrix-weighted anisotropic Besov-type and Triebel-Lizorkin-type spaces

Tengfei Bai, Pengfei Guo, Jingshi Xu

We introduce matrix-weighted anisotropic Besov-type and Triebel-Lizorkin-type spaces associated with an expansive matrix . Inspired by the $\A_p$-dimensions of matrix weight of…

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…

Precompactness in matrix weighted Bourgain-Morrey spaces

Tengfei Bai, Jingshi Xu

In this paper, we introduce matrix weighted Bourgain-Morrey spaces and obtain two sufficient conditions for precompact sets in matrix weighted Bourgain-Morrey spaces. We prove that…

On matrix weighted Bourgain-Morrey Triebel-Lizorkin spaces

Tengfei Bai, Pengfei Guo, Jingshi Xu

We introduce the homogeneous (inhomogeneous) matrix weighted Bourgain-Morrey Triebel-Lizorkin spaces and obtain their equivalent norms. We also obtain their characterizations by Pe…
