Homotopic convex
WebQuestion 52.1. A subset A of Rn is said to be star convex if for some point a 0 of A, all the line segments joining a 0 to other points in A lie in A.

WebRecall that an n-simplex is the convex hull of a set of n+ 1 points in the Rm, for some m 0. A face of the simplex is the convex hull of a subset of these points. Moreover a (geometric) simplicial complex is a set of simplices in some Rm, such that the intersection of two simplices is a face of each simplex or empty. We can stretch a simplex WebThis homotopy between fand gis called the straight-line homotopy for the fact that it moves from f(x) to g(x) along the straight line connecting them. Example 1.9.
