Abstract:
The reason why in 1+1 dimensions "Fermi" fields can be expressed in terms of "Bose" fields (so-called "bosonization") is clarified in the case of the Thirring model by solving it on the basis of the Lagrangian formalism. It is characteristic invariance of the Lagrangian density under a special phase transformation of the second kind that allows the "bosonization" mentioned above. The soliton and the topological quantization of the charge in the massive Thirring model are briefly discussed.
