[HTML][HTML] Reduced convex bodies in Euclidean space—a survey

M Lassak, H Martini - Expositiones Mathematicae, 2011 - Elsevier
A convex body R in Euclidean space Ed is called reduced if the minimal width Δ (K) of each
convex body K⊂ R different from R is smaller than Δ (R). This definition yields a class of …

Reduced convex bodies in finite dimensional normed spaces: a survey

[PDF][PDF] Reduced spherical polygons

M Lassak - Colloq. Math, 2015 - academia.edu
For every hemisphere K supporting a spherically convex body C of the d-dimensional
sphere Sd we consider the width of C determined by K. By the thickness∆(C) of C we mean …

Is a complete, reduced set necessarily of constant width?

R Brandenberg, BG Merino, T Jahn… - Advances in Geometry, 2019 - degruyter.com
Is it true that a convex body K being complete and reduced with respect to some gauge body
C is necessarily of constant width, ie does it satisfy K− K= ρ (C− C) for some ρ> 0? We prove …

On pyramids and reducedness

G Averkov, H Martini - Periodica Mathematica Hungarica, 2008 - akjournals.com
A convex body K in ℝ d is said to be reduced if the minimum width of each convex body
properly contained in K is strictly smaller than the minimum width of K. We study the question …

[PDF][PDF] On the volume of the convex hull of d+ 1 segments in Rd

G Averkov, H Martini - Publ. Math. Debrecen, 2008 - Citeseer
Let d≥ 2, m≥ d, and u1,..., um be non-zero vectors linearly spanning Rd. We consider the
class P (u1,..., um) of convex polytopes P in Rd such that P= conv (I1∪...∪ Im), where, for j …
