Minkowski inequality in Cartan-Hadamard manifolds

, 2023
Using harmonic mean curvature flow, we establish a sharp Minkowski type lower bound for total mean curvature of convex surfaces with a given area in Cartan-Hadamard 3-manifolds.

Lifting cubics into (Minkowski) space

, 2004
For a given planar cubic c(t) = [X(t), Y (t)] T, we identify the system of Pythagorean hodograph (PH) cubics of the form [X(t), Y (t), Z(t)] T in Euclidean and in Minkowski spaces.

On Ruled Surfaces in three-dimensional Minkowski Space

, 2010
In a Minkowski three dimensional space, whose metric is based on a strictly convex and centrally symmetric unit ball , we deal with ruled surfaces Φ in the sense of E. Kruppa.

General volumes in the Orlicz-Brunn-Minkowski theory and related Minkowski problems

, 2019
The Minkowski problem is one of the core problems in convex geometry, which aims to characterize the surface area measures of convex bodies in Rn. Various extensions and their dual have been introduced in recent years, among which the newly proposed ...

Brunn-Minkowski inequalities for sprays on surfaces

We propose a generalization of the Minkowski average of two subsets of a Riemannian manifold, in which geodesics are replaced by an arbitrary family of parametrized curves.
