WebA special case of Theorem 8.1 is the well-known Hardy Inequality. Indeed, let ϕ (x) ≡ xp, α > 0, β > 0, and Then ( 8.1) becomes (8.2) or (8.3) for either p > 1 or p < 0. If 0 < p < 1, then the reverse of the inequalities in ( 8.2) and ( 8.3) is valid. Hardy's inequality was first published and proved (at least the discrete version with a worse constant) in 1920 in a note by Hardy. The original formulation was in an integral form slightly different from the above. See more Hardy's inequality is an inequality in mathematics, named after G. H. Hardy. It states that if $${\displaystyle a_{1},a_{2},a_{3},\dots }$$ is a sequence of non-negative real numbers, then for every real number p > 1 … See more Integral version A change of variables gives Discrete version: from the continuous version Assuming the right … See more • Carleman's inequality See more • "Hardy inequality", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more The general weighted one dimensional version reads as follows: • If $${\displaystyle \alpha +{\tfrac {1}{p}}<1}$$, then See more In the multidimensional case, Hardy's inequality can be extended to $${\displaystyle L^{p}}$$-spaces, taking the form where $${\displaystyle f\in C_{0}^{\infty }(R^{n})}$$, … See more 1. ^ Hardy, G.

WebAbstract We prove Hardy-type inequalities for a fractional Dunkl–Hermite operator, which incidentally gives Hardy inequalities for the fractional harmonic oscillator as well. The idea is to use h -harmonic expansions to reduce the problem in the Dunkl–Hermite context to the Laguerre setting. WebSep 6, 2024 · A technical step in proving Hardy's inequality. However, it doesn't seem like the constant 4 is explicitly computed in Evans, and moreover it may be improved if the domain of u is not convex. In the dimension 1 variant, it is optimal, and you can refer to Computing the best constant in classical Hardy's inequality. WebFeb 1, 2024 · We prove optimal improvements of the Hardy inequality on the hyperbolic space. Here, optimal means that the resulting operator is critical in the sense of Devyver, Fraas, and Pinchover (2014), namely the associated inequality cannot be further improved. homes in an mls season
