Abstract

The Hardy–Littlewood–Pólya inequality of majorization is extended for \(\mathbf {\omega }\)\(\textbf{m}\)–star-convex functions to the framework of ordered Banach spaces. Several open problems which seem to be of interest for further extensions of the Hardy–Littlewood–Pólya inequality are also included.
