“…also [11,Corollary 6]). The assertions for the classes L p,α,loc (R) follow from the corresponding assertions for L p,α (R) and the fact that the kernel of the generalized translation operator is finite [11,Corollary 5]. The assertions for the classes W (r) p,α (R) and W (r) p,α,loc (R) are obvious since the operators T y and Λ commute.…”
