Two weighted norm inequalities for Riesz potentials and uniform \(L^ p\)- weighted Sobolev inequalities. (English) Zbl 0736.42015
The author proves a two-weighted norm inequality for the fractional maximal operator and the corresponding inequality for Riesz potentials of fractional order. These results also yield some inequalities coupling a weighted \(L^ p\)-norm of a function and a weighted \(L^ p\)-norm of its derivative.
