In this paper we mainly study two problems based on the traditional Hardy inequal-ity. In view of Maz’ya and Jesper Tidblom we present a different proof, which enable us to improve those constant in front of the remainder term. Firstly, in generalized two-dimensional sector, if the parameter γ=1,p=2how to improve the formula of the coefficient of a Hardy inequality shaped like:In addition, we also study if the p(p>1) changes, how the parameters γ(0<γ≤1) which coefficient of the1/4dimensional plane will be. |
