Additive perturbations, specifically, matrix Uvarov transformations formatrix orthogonal polynomials, are under consideration. Christoffel-Uvarovformulas are deduced for the perturbed biorthogonal families, along with theirmatrix norms. These formulations are expressed in terms of the spectral jets ofthe Christoffel-Darboux kernels.
