Sobolev type spaces on spaces of homogeneous type: different descriptions and embedding theorems
Abstract.
We consider the scale of Sobolev type spaces W_eta^p on metric spaces, that depends on the modulus of continuity eta and p > 1. We give different descriptions for these spaces. In case eta(t)=t^s common descriptions were given by D. Yang. Also we obtain for these spaces embedding theorem of Sobolev type, which extends the result of V. Kolyada onto spaces of homogeneous type.
