Abstract
For mappings of a topological space \((X,\mu)\) to a Banach space \((Y,|\cdot|_{Y})\), we define analogs of Sobolev classes \(W_{p}^{r}(X;Y)\), \(r=1,2,\dots,\) as well as Sobolev–Slobodetsky classes \(W_{p}^{r}\), \(r\in[1,\infty)\), and their generalizations. We prove theorems on the embedding into the scale of Lebesgue spaces \(L_{q}\) and into Orlizc spaces corresponding to rapidly increasing generating functions; other properties of Sobolev functions are studied as well.
