Let I = (0, ∞) and let v, u be almost everywhere positive and locally integrable functions on the interval I.Let 1 < p, q < ∞, and p = p p–1 Let us denote byLp,v ≡ Lp(v, I) the set of measurable functions f on I for which f p,v = ∞f (x) pv(x) dx 1 p < ∞.Let W be a positive, strictly increasing, and locally absolutely continuous function on the interval I
The boundedness and compactness of operator (1.2) from Lp,w to Lq,v is obtained in the paper
The main goal of the paper is to establish the criteria for the boundedness and compactness of operator (1.1) from Lp,w to Lq,v for the following relations of the space parameters 1 < p ≤ q < ∞
Summary
The boundedness and compactness of operator (1.2) from Lp,w to Lq,v is obtained in the paper The boundedness and compactness of operator (1.2) were obtained in the paper [8] when the upper limit of the integral is a function. The main goal of the paper is to establish the criteria for the boundedness and compactness of operator (1.1) from Lp,w to Lq,v for the following relations of the space parameters 1 < p ≤ q < ∞. 3 Boundedness of the operator Tα,β The main result of this section is the following.
