Abstract: Dyson-Schwinger equations for the Un x Un symmetric matrix sigma modelreformulated with two auxiliary fields in a background breaking the symmetry toUn are studied in the so-called bare vertex approximation. A large n solutionis constructed under the supplementary assumption so that the scalar componentsare much heavier than the pseudoscalars. The renormalizability of the solutionis investigated by explicit construction of the counterterms.
