Figure 1From: The existence of equilibrium in a simple exchange modelThe K -triangulation of 2-simplexS=〈 v 1 , v 2 , v 3 〉with grid size 6. The small triangles are members of the triangulation K(S,6). The number at a vertex of a simplex in K(S,6) is the value of l assigned to the vertex and one sees that l satisfies the assumptions of Lemma 1. The sequence of simplices σ 1 ,…, σ 12 meets the requirements described in the proof of Lemma 1.Back to article page
