Stability of the -Poincaré inequality for the Lebesgue measure and Gaussian probability measure with explicit geometric dependence and applications to spectral gaps

Nurgissa Yessirkegenov, Amir Zhangirbayev

The paper establishes stability estimates for the L^p‑Poincaré inequality under Lebesgue and Gaussian measures with explicit geometric constants, and applies these results to obtai…

Sharp forms and quantitative stability for general weighted discrete -Hardy inequalities

Nurgissa Yessirkegenov, Amir Zhangirbayev

The paper derives a sharp remainder term for general weighted discrete p‑Hardy inequalities and shows that the inequality’s deficit quantitatively controls the distance to the set…

Sharp remainder formulae for general weighted Hardy and Rellich type inequalities for

Yerkin Shaimerdenov, Nurgissa Yessirkegenov, Amir Zhangirbayev

Inspired by the work of Cossetti and D'Arca [CD25], we show that the general weighted -Hardy type inequalities [CD25, Theorems 1.1 and 1.2] and the corresponding identities…

Sharp remainder terms and stability of weighted Hardy-Poincaré and Heisenberg-Pauli-Weyl inequalities related to the Baouendi-Grushin operator

Yerkin Shaimerdenov, Nurgissa Yessirkegenov, Amir Zhangirbayev

In this paper, we obtain sharp remainder terms for the Hardy-Poincaré inequalities with general non-radial weights in the setting of Baouendi-Grushin vector fields (see Theorem 2.…

Refined general weighted -Hardy and Caffarelli-Kohn-Nirenberg type inequalities and identities related to the Baouendi-Grushin operator

Nurgissa Yessirkegenov, Amir Zhangirbayev

In this paper, we present a sufficient condition on a pair of nonnegative weights and such that we have a general weighted -Hardy type identity. The result, for a ce…

Sharp remainder of the -Poincaré inequality for Baouendi-Grushin vector fields

Kuralay Apseit, Nurgissa Yessirkegenov, Amir Zhangirbayev

In this paper, we establish a sharp remainder formula for the Poincaré inequality for Baouendi-Grushin vector fields in the setting of for complex-valued functions. In spe…
