Abstract
The paper is devoted to spaces of generalized smoothness on so-called $h$-sets. First we find quarkonial representations of isotropic spaces of generalized smoothness on $\mathbb{R}^n$ and on an $h$-set. Then we investigate representations of such spaces via differences, which are very helpful when we want to find an explicit representation of the domain of a Dirichlet form on $h$-sets. We prove that both representations are equivalent, and also find the domain of some time-changed Dirichlet form on an $h$-set.
