Abstract
In this paper we introduce some new Lizorkin–Triebel type spaces of variable smoothness. Here the smoothness lies in a new weighted class. We give some equivalent quasinorms and their characterizations via oscillations. We show that the box splines and tensor-products of \( B \)-splines are suitable to obtain the stable representations of functions of these spaces.
