Weight Inequalities for Singular Integrals Defined on Spaces of Homogeneous and Nonhomogeneous Type

Optimal sufficient conditions are found in weighted Lorentz spaces for weight functions which provide the boundedness of the Calder\'{o}n--Zyg\-mund singular integral operator defined on spaces of homogeneous and nonhomogeneous type
