SOME NEW MULTIDIMENSIONAL HARDY-TYPE INEQUALITIES WITH KERNELS VIA CONVEXITYJames A. Oguntuase and Philip DurojayeDepartment of Mathematics, University of Agriculture, P.M.B. 2240 Abeokuta, Nigeria and Department of Mathematics and Statistics, Federal Polytechnic, P.M.B. 50 Ilaro, NigeriaAbstract: We prove some new multidimensional Hardy-type inequalities involving general Hardy type operators with positive kernels for functions $\phi$ which may not necessarily be convex but satisfy the condition $A\psi(\x)\leq\phi(\x)\leq B\psi(\x)$, where $\psi $ is convex. Our approach is mainly the use of convexity argument and the results obtained are new even for the one-dimensional case and also unify and extend several inequalities of Hardy type known in the literature. Keywords: Multidimensional Hardy type inequalities, convexity argument, general Hardy type operator, kernels, weight functions Classification (MSC2000): 26D10; 26D15 Full text of the article: (for faster download, first choose a mirror)
