Abstract

This article is the first part of two works of the authors on the same topic. Let be a general expansive matrix on and a Muckenhoupt -weight with respect to . In this article, the authors first characterize the weighted anisotropic Triebel–Lizorkin space in terms of Peetre maximal functions or Lusin-area functions defined via Fourier analytical tools. As an application, the authors also establish a characterization of with smoothness order via a Lusin-area function involving the difference between and its ball average

where denotes the set of all eigenvalues of ,

denotes the step homogeneous quasi-norm associated with and, for any and , .
