Resumo:
We analyse the non-linear realization of Lorentz transformation as proposed heuristically by Albano and Dresden and we built a space that enables us to deduce analytically their transformation. The central point of our construction is the space of sections $\Gamma(M) \ni s(x): M \rightarrow R^4$ which allow us to deﬁne a curved metric in spacetime.
