Let X X T 2 3 w x C be a positive hermitian X P 0 matrix-valued function on the bitorus with T 2 log det X b ΓI and T 2 kXk `I. Then X is the v 1 -limit of p j p Γ j , where p j is a x Γ x j rectangular bi-analytic matrix function. A continuous and strictly positive hermitian X X T 2 3 w x may be fa
