A conjectured local Liakopoulos–Meyer inequality for convex bodies

About 1 year old · traced to

Let KK be a convex body in Rn\mathbb{R}^n and let (σ1,…,σm)(\sigma_1,\dots,\sigma_m) be an ss-cover of σ⊂[n]\sigma\subset[n]. For each τ⊂[n]\tau\subset[n], let HτH_\tau denote the coordinate subspace associated with τ\tau, and let ∣⋅∣|\cdot| denote volume. Local Liakopoulos–Meyer conjecture. Then

∣K∣m−smax⁡x∈Rn∣K∩(x+Hσ⊥)∣s≥∏j=1m(∣σ∣−∣σj∣)!∣σ∣!m−s∏j=1m∣K∩Hσj⊥∣.|K|^{m-s}\max_{x\in\mathbb{R}^n}|K\cap(x+H_\sigma^\bot)|^s\geq \frac{\prod_{j=1}^m(|\sigma|-|\sigma_j|)!}{|\sigma|!^{m-s}}\prod_{j=1}^m|K\cap H_{\sigma_j}^\bot|.

This is presented as a conjectural strengthening or formulation of the preceding inequalities for arbitrary convex bodies and ss-covers; the supplied text does not indicate whether it has been proved or remains open.
