abstract

The Brunn-Minkowski inequality states that for bounded measurable sets $A$ and $B$ in $\mathbb{R}^n$, we have $|A+B|^{1/n} \geq |A|^{1/n}+|B|^{1/n}$. Also, equality holds if and only if $A$ and $B$ are convex and homothetic sets in $\mathbb{R}^d$. The stability of this statement is a well-known problem that has attracted much attention in recent years. This paper gives a conclusive answer by proving the sharp stability result for the Brunn-Minkowski inequality on arbitrary sets.

  1. Stability of the $L^{p}$-Poincar\'e inequality for the Lebesgue measure and Gaussian probability measure with explicit geometric dependence and applications to spectral gaps

    math.AP 2026-02 conditional novelty 7.0 of 10

    An explicit geometric stability constant is derived for the L^p-Poincaré inequality on convex domains, yielding a new but partially non-explicit spectral-gap bound for the p-Laplacian.

  2. Quantitative stability for the Brascamp-Lieb inequality and moment measures

    math.FA 2025-11 conditional novelty 7.0 of 10

    For any convex potential, the L1 distance from a function to the Brascamp-Lieb optimizer manifold is controlled by the square root of its deficit, with a dimension-only constant independent of the potential.

  3. Sharp gradient stability for a class of Hardy-Sobolev-Maz'ya inequalities

    math.AP 2025-08 conditional novelty 7.0 of 10

    For 3<=k<=n-1, 1<p<n, the deficit in the Hardy-Sobolev-Maz'ya inequality is bounded below by a constant times the gradient distance to the extremal manifold raised to the power max{2,p}, and this exponent is optimal.
