-Caffarelli-Kohn-Nirenberg inequalities and their stabilities

AX Do, J Flynn, N Lam, G Lu - arXiv preprint arXiv:2310.07083, 2023 - arxiv.org
We establish a general identity (Theorem 1.2) that implies both the $ L^{p} $-Hardy identities
and the $ L^{p} $-Caffarelli-Kohn-Nirenberg identities (Theorems 1.3 and 1.4) and $ L^{p} …

Hardy-Poincaré-Sobolev type inequalities on hyperbolic spaces and related Riemannian manifolds

J Flynn, N Lam, G Lu - Journal of Functional Analysis, 2022 - Elsevier

substantial improvements of Hardy inequalities for the operators− Δ H−(N− 1) 2 4 on the …

Hardy's identities and inequalities on Cartan-Hadamard manifolds

J Flynn, N Lam, G Lu, S Mazumdar - The Journal of Geometric Analysis, 2023 - Springer
We study the Hardy identities and inequalities on Cartan-Hadamard manifolds using the
notion of a Bessel pair. These Hardy identities offer significantly more information on the …

[HTML][HTML] Lp Hardy's identities and inequalities for Dunkl operators

J Wang - Advanced Nonlinear Studies, 2022 - degruyter.com
The main purpose of this article is to establish the L p Hardy's identities and inequalities for
Dunkl operator on any finite balls and the entire space RN. We also prove Hardy's identities …

A new approach to weighted Hardy-Rellich inequalities: improvements, symmetrization principle and symmetry breaking

AX Do, N Lam, G Lu - arXiv preprint arXiv:2310.06637, 2023 - arxiv.org
We investigate necessary and sufficient conditions on the weights for the Hardy-Rellich
inequalities to hold, and propose a new way to use the notion of Bessel pair to establish the …

[HTML][HTML] A generic functional inequality and Riccati pairs: an alternative approach to Hardy-type inequalities

S Kajántó, A Kristály, IR Peter, W Zhao - Mathematische Annalen, 2024 - Springer

multiplicative forms, that produces well known and genuinely new Hardy-type inequalities …

-Hardy identities and inequalities with respect to the distance and mean distance to the boundary

J Flynn, N Lam, G Lu - arXiv preprint arXiv:2310.18758, 2023 - arxiv.org
Firstly, this paper establishes useful forms of the remainder term of Hardy-type inequalities
on general domains where the weights are functions of the distance to the boundary. For …
