3. The theorem can be refined to include a chain of ideals of " R " ( equivalently, closed subsets of " X " ) that are finite over the affine coordinate subspaces of the appropriate dimensions.
4. Taking their conjugates, we see that z is a weighted sum with positive coefficients that sum to one, or the barycenter on affine coordinates, of the complex numbers a _ i ( with different mass assigned on each root whose weights collectively sum to 1 ).
