Some Generalisations and Refinements of the Hardy Inequality

Part of the Mathematics and Its Applications book series (MAIA, volume 430)


Some recent results connected with the one-dimensional Hardy operator are given. Namely, some fractional order analogues of the classical Hardy inequality are discussed, and results concerning the two-dimensional Hardy operator are extended to Hardy operators defined on 1ℝ M × ℝ N . The main tools are the interpolation theory and some direct approaches for the fractional order case, and a recently derived N-dimensional Hardy inequality for operators on ℝ N .
