The Generation of Convex Sets—Convex Hulls

1979
In this chapter a new operation—comparable in importance to the interior and closure operations—is introduced. It operates on each set S to produce a convex set—the convex hull of S—acting as a veritable machine for the generation of convex sets. In effect it expands an arbitrary set into a convex set in the simplest possible way.

Note on Generalized Convex Spaces

2011
Some examples are given to show that some known generalized convex spaces are so abstract that some basic properties related to the convexity are lost. In order to improve the convexity structure for applications, the concepts of path-convex space, path-convex set and path-convex function are introduced. And their properties are discussed.

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.

Generalizations of convexity

1978
I consider four generalizations of the concept of a convex set in Rd. A subset X of R belongs to the family T(a) if for all x, y e X ax + (1 -a)y e X where a e R. Properties of elements of T(a) are considered in Chapter 1.Also in Chapter 1 a planar generalization of the family T(a) is considered.
