Abstract: This paper deals with a generalization of 2-microlocal spaces in the sense of weighted Besov spaces. We define 2-microlocal Besov spaces $B^{s,{mloc}}_{pq}(\\mathb{R}^n,w)$ and describe first properties.
The key theorem is the local means characterization for these spaces. Using this characterization we prove some conclusions as a pointwise multiplier assertion and the invariance of the spaces $B^{s,{mloc}}_{pq}(\\mathb{R}^n,w)$ under the action of diffeomorphisms.

Keywords: Besov spaces, 2-microlocal spaces, local means
