The theorem guarantees the existence of a d-dimensional analytic manifold M and a real analytic map
g:M∋u↦w∈W
such that for each coordinate Mα of M one can write
K(g(u))=u2k11…u2kdd...
I’m a bit confused here. First, I take it that α labels coordinate patches? Second, consider the very simple case with d=2 and K(w)=w21+w22. What g would put K into the stated form?
