We obtain eigenvalue perturbation results for a factorised Hermitian matrix H = GJ G \* where J 2 = I and G has full row rank and is perturbed into G + Ξ΄G, where Ξ΄G is small with respect to G. This complements the earlier results on the easier case of G with full column rank. Applied to square facto
