The connectivity and measure theoretic properties of the skeleta of convex bodies in Euclidean space are discussed, together with some long standing problems and recent results.

A general geometric construction for affine surface area

Elisabeth Werner (1999)

Studia Mathematica

Similarity:

Let K be a convex body in n and B be the Euclidean unit ball in n . We show that l i m t 0 ( | K | - | K t | ) / ( | B | - | B t | ) = a s ( K ) / a s ( B ) , where as(K) respectively as(B) is the affine surface area of K respectively B and K t t 0 , B t t 0 are general families of convex bodies constructed from K,B satisfying certain conditions. As a corollary we get results obtained in [M-W], [Schm], [S-W] and [W].

A measure of axial symmetry of centrally symmetric convex bodies

Marek Lassak, Monika Nowicka (2010)

Colloquium Mathematicae

Similarity:

Denote by Kₘ the mirror image of a planar convex body K in a straight line m. It is easy to show that K*ₘ = conv(K ∪ Kₘ) is the smallest by inclusion convex body whose axis of symmetry is m and which contains K. The ratio axs(K) of the area of K to the minimum area of K*ₘ over all straight lines m is a measure of axial symmetry of K. We prove that axs(K) > 1/2√2 for every centrally symmetric convex body and that this estimate cannot be improved in general. We also give a formula for...
