Web2 are two convex sets, then S 1 ∩S 2 is a convex set. Proof: Let x 1,x 2 ∈ S 1 ∩S 2. Now since x 1 and x 2 belong to S 1 (which is convex), any convex combination of them lies in S 1. Similarly we can say that this convex combination of x 1 and x 2 lies in S 2. Thus the convex combination lies in S 1 ∩S 2. Thus S 1 ∩S 2 is convex ...
