abstract

We show that the only even, smooth, convex solutions to a class of isotropic mixed Christoffel-Minkowski type problems are origin-centred spheres, which, in particular, answers a question of Firey 74 in the even isotropic case about kinematic measures. Employing the Heintze-Karcher inequality, we prove that the only smooth, strictly convex solutions to a large class of Minkowski type problems are origin-centred spheres. Immediate corollaries are the uniqueness of solutions to the isotropic Orlicz-Minkowski problem and the isotropic $L_p$-Gaussian-Minkowski problem when $p\geq 1$.

    Weighted centro-affine Poincaré inequalities yield L0 and Lp Brunn–Minkowski inequalities for dual quermassintegrals of unconditional convex bodies, with equality only for dilates.

  2. Uniqueness of solutions to the isotropic $L_{p}$ Gaussian Minkowski problem

    math.AP 2024-12 accept novelty 6.0 of 10

    For -(n+1)<p<-1, isotropic Lp Gaussian Minkowski solutions with R(K)≤1 are unique and spherical, without assuming the body is origin-centered.
