Resumen:
Nonlinear realizations of the SO(4,2) group are discussed from the point ofview of symmetries. Dynamical symmetry breaking is introduced. One linearand one quadratic model in curvature are constructed. Coherent states of theKlauder?Perelomov type are defined for both cases taking into account the cosetgeometry. A new spontaneous compactification mechanism is defined in the subspace invariant under the stability subgroup. The physical implications of thesymmetry breaking in the context of nonlinear realizations and direct gauging areanalyzed and briefly discussed
