Weight criteria for the boundedness and compactness of generalized Hardy-type operators T f ( x ) = u 1 ( x ) ∫ { ϕ ( y ) ≤ ψ ( x ) } f ( y ) u 2 ( y ) v 0 ( y ) d μ ( y ) x ∈ X in Orlicz-Lorentz spaces defined on measure spaces is investigated where the functionsϕ, ψ, u1,u2,v0are positive measurable functions. Some sufficient conditions of boundedness ofandare obtained on Orlicz-Lorentz spaces. Furthermore, we achieve sufficient and necessary conditions forTto be bounded and compact from a weighted Lorentz spaceto another. It is notable that the function spaces concerned here are quasi-Banach spaces instead of Banach spaces.
