SIMPLICIAL SUBDIVISION

Simplicial subdivision - Given a simplex, S, its simplicial subdivision is a collection of simplices, say (T_i) such that \/_i(T_i) = S and for any i and j, either the intersection T_i/\T_j is empty or equals the closure of a common face. The mesh of the subdivision is the diameter of the largest sub-simplex. This arises in a fixed point approach to compute an economic equilibrium.
