Abstract: On $s$-homogeneous metric spaces with measure for Sobolev-type functions with "smoothness" $\alpha \le 1$ we prove the property $s/\alpha$- absolute continuity, in the case when the characteristics that define "smoothness" belong to the corresponding Lorentz space.

Keywords: Lorentz space, Sobolev type functions, homogeneous metric spaces, absolute continuity.
