For 1 ⩽ k < ∞ and 1 ⩽ p ⩽ q ∞, the problem of finding the best constant C p q in the weighted inequality( ∫ 0 ∞|I k f ( x )| q| u ( x )| q d x )1 / q ⩽ C p , q( ∫ 0 ∞| f ( x )| p| υ ( x )| p d x )1 / p , involving the Riemann‐Liouville integrals of the formI k f ( x ) = 1 Γ ( k )∫ 0 x( x ‐ t )k ‐ 1 f ( t ) d t , is considered.
