WebMar 22, 2024 · 1 Answer. Let us show that S ≡ { ∑ i = 1 m λ i ω i: λ i ≥ 0 ∀ i, ∑ λ i = 1, ω i ∈ Ω i ∀ i } is a convex set. Once this is done it follows that it contains c o ( ∪ i = 1 m Ω i) because it contains each Ω i. Also this set is obviously contained in c o ( ∪ i = 1 m Ω i) so the proof will be complete.
