Método de renormalización por sustracción de Taylor en el modelo DFR

The noncommutative space-time model introduced by Doplicher, Fredenhagen and Roberts (DFR), is based on commutation relations of the form [qu, qv] = Lp Quv for the quantum coordinate operators qu, where Lp represents a length scale and Quv is a tensor operator. In this thesis, the DFR model, and in...
