^{2}corrections to their anomalous dimensions and show the absence of instantonic contributions thereof. Ratios of the resulting expressions are irrational numbers, even in the large N limit where, however, we observe the expected decoupling...

^{4}using the N=1 superfield formalism. We confirm the interpretation of short-distance logarithmic behaviours in terms of anomalous dimensions of unprotected operators exchanged in the intermediate channels and we determine the two-loop contribution to the anomalous dimension...

*R*-matrix relations are derived for the group-valued chiral vertex operators in the SU(

*n*) WZNW model from the KZ equation for a general four-point function including two step operators. They fit the exchange relations of the

*U*

_{ q }(sl

_{ n }) covariant quantum matrix algebra derived previously by solving the dynamical Yang–Baxter equation. As a byproduct, we extend the regular basis introduced...

_{2}projected models which exist only for even values of the level k and correspond to branes at D-type orbifold singularities. The resulting...
