Claims

C1strongest claim

Elements of representation and solution of the minimization problem at a point are presented on the Minkowski-Cohn moduli surface.

C2weakest assumption

That the Minkowski-Cohn moduli surface admits effective pointwise minimization via the outlined representation elements, without details on convergence or global behavior.

C3one line summary
