| Abstract: | The generalized Thirring model with impurity coupling is defined ontwo-dimensional noncommutative space-time, a modified propagator and freeenergy are derived by means of functional integrals method. Moreover,quantum fluctuations and excitation energies are calculated on two-dimensional black hole and soliton background. |
