Convex ball
WebThe convex hull of the red set is the blue and red convex set. In geometry, the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a Euclidean space, or equivalently as the set of all ... WebConvex sets This chapter is under construction; the material in it has not been proof-read, and might contain errors (hopefully, nothing too severe though). We say a set Cis convex if for any two points x;y2C, the line segment (1 )x+ y; 2[0;1]; lies in C. The emptyset is also regarded as convex. Notice that while defining a convex set,
