## Abstract Let __I__ = [__a__ , __b__ ] βŠ‚ ℝ, let 1 < __q__ ≀ __p__ < ∞, let __u__ and __v__ be positive functions with __u__ ∈ __L__ ~__p__ β€²~ (__I__ ) and __v__ ∈ __L__ ~__q__~ (__I__ ), and let __T__ : __L__ ~__p__~ (__I__ ) β†’ __L__ ~__q__~ (__I__ ) be the Hardy‐type operator given by equation
