Projected Area of Convex Bodies

Nature, 1948
IN connexion with photometric determination of specific surface of finely divided material, it is essential to know the relation between the projected area of particles, which is actually measured, and the corresponding surface area. The solution of this problem was first given by A.

Convolutions, Transforms, and Convex Bodies

Proceedings of the London Mathematical Society, 1999
The paper studies convex bodies and star bodies in \(\mathbb R^n\) by using Radon transforms on Grassmann manifolds, \(p\)-cosine transforms on the unit sphere, and convolutions on the rotation group of \(\mathbb R^n\). It presents dual mixed volume characterizations of \(i\)-intersection bodies and \(L_p\) balls which are related to certain volume ...

Chord Functions of Convex Bodies

Journal of the London Mathematical Society, 1987
The k-chord function \(f\) \(k_ p\) of a set E, star-shaped at some point p, in \({\mathbb{R}}^ 2 \)is defined as follows (k\(\in {\mathbb{Z}})\). Suppose that \(t\in [0,\pi]\) and L is a line making an angle t with the x-axis. If \(L\cap E=\emptyset\), then \(f\) \(*_ p(t)=0\).

Generalized Convex Bodies of Revolution

Canadian Journal of Mathematics, 1967
The figures studied in this paper are special convex bodies in Euclidean three-dimensional space which we shall call generalized convex bodies of revolution (GCBR). Such a set is obtained by the following procedure. Let K1 be a convex body of revolution and let x, y, z denote Cartesian coordinates in a system for which the z-axis is the axis of K1.

Convex Bodies with Homothetic Sections

Bulletin of the London Mathematical Society, 1991
Let \(K\subset\mathbb{E}^{n+1}\) (\(n\geq 2)\) be a convex body, let \(p_ 0\in K\), and suppose that all \(n\)-sections through \(p_ 0\) are affinely equivalent. For odd \(n\), it is still unknown whether \(K\) must be an ellipsoid. The author proves the following weaker versions. If all \(n\)- sections of \(K\) through \(p_ 0\) are affinely equivalent,
