As one of the results of this manuscript, we show that for any logconcave measure μ on R, any pair of symmetric convex sets K and L, and any λ ∈ [0, 1], μ((1− λ)K + λL)n ≥ (1− λ)μ(K)n + λμ(L)n , where cn ≥ n−4−o(1). This constitutes progress towards the Dimensional BrunnMinkowski conjecture (see Gardner, Zvavitch [45], Colesanti, L, Marsiglietti [27]). Moreover, our bound improves for various special classes of log-concave measures. However, most of the paper is dedicated to studying sharp…

In this paper we provide a comparison result between the solutions to the torsion problem for the Hermite operator with Robin boundary conditions and the one of a suitable symmetrized problem.
A universal bound in the dimensional Brunn-Minkowski inequality for log-concave measures
We show that for any log-concave measure μ on R, any pair of symmetric convex sets K and L, and any λ ∈ [0, 1], μ((1 − λ)K + λL) ≥ (1 − λ)μ(K) + λμ(L) , where cn ≥ n. This constitutes progress
