Summary
The Liouville, sine-Gordon and nonlinear σ-models in 2 dimensions are obtained from a common formalism. The topological charge of the Liouville model is found to be zero, if the definition of the topological charge of the sine-Gordon model is utilized.
Riassunto
I modelli σ di Liouville, sine-Gordon e non lineare in due dimensioni sotto ottenuti da un formalismo comune. Si trova che carica topologica del modello di Liouville è uguale a zero, se si utilizza la definizione della carica topologica del modello sine-Gordon.
