WebIf S1 and S2 are convex sets, prove that their intersection S1∩S2 is also a convex set. Discussion You must be signed in to discuss. Video Transcript Okay, So we want to take to convex sets S. One and S two only. Want to show that the intersection S. One intersects S. Two is also a convex set. So what do we need to do? 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,

Webso C is convex. (A similar argument holds for an infinite number of sets.) This is not true for the union of convex sets. Let C1:= {0} and C2:= {1} as subsets of R. Both sets are clearly convex, but the union of them is not convex. 1.2 MidpointConvex A set is C ⊆ Rn is midpointconvex if whenever x,y ∈ C we have 1 2 (x +y)∈ C. It is clear ... Webis called a solution set. Every solution set is convex. • An m×m matrix is a stochastic matrix if all its entries are nonnegative and each row sums to one. The set of stochastic matrices is a convex set. 1.1.7 Exercise (Elementary properties of convex sets) Prove the follow-ing. 1. The intersection of a family of convex sets is convex. 2.
