The Mahler conjecture for general (non-symmetric) convex bodies
Theorem 1.1: for every n≥1 and every convex body K⊂Rn with Santalo point s(K), ∣K∣∣(K−s(K))∘∣≥(n+1)n+1/(n!)2, with equality iff K is a simplex; no symmetry or boundary regularity is assumed. The proof goes through Klartag's cone and Laplace-transform correspondence, Gaussian-averaged nearest-point projections onto a cone and its dual, and a spectral comparison whose scalar estimates rest on finite rational certificates with a released Python runner. Corollary: the sharp functional inequality ∫e−φ∫e−φ∗≥en for convex φ, via Fradelizi-Meyer, and an entropy-transport bound under an extra hypothesis. It does not give the symmetric constant 4n/n!, which is a separate entry.
