We compute the virtual corrections without using any approximation and we take into account all the relevant graphs with the inclusion of those omitted in the previous approximative calculations.

The idea is to reformulate them on the world sheet, and then to apply the classical (meanfield) approximation, with two goals: to show that the ground state of the model is a solitonic configuration on the world sheet, and the quantum fluctuations around the soliton lead to the formation of a transverse...

More precisely we show that the leading quantum corrections in the fusion of transfer matrices induce the correct...
