Abstract:
A simple characterization is given for two-weight norm inequalities for generalized Hardy operators ${T_\varphi }f(x) = \smallint _0^x\varphi (\tfrac {t}{x})f(t)dt$, where $\varphi :(0,1) \to (0,\infty )$ is nonincreasing and satisfies $\varphi (ab) \leq D[\varphi (a) + \varphi (b)]$ for $0 < a,b < 1$. Included in particular are the Riemann-Liouville fractional integrals.References
