Axial-vector properties of the nucleon with 1/Nc corrections in the solitonic SU(3)-NJL model.

Within the semibosonized SU(3)-NJL model the mass splittings of baryons and the axial vector coupling constants of the nucleon are evaluated. The mass splittings of the hyperons are reproduced with great accuracy if second order corrections in
