We obtain an exact solution for the Einstein’s equations with cosmological constant coupled to a scalar, static particle in static, ”spherically” symmetric background in 2 + 1 dimensions. ————————————————————————————

Using ODE techniques we prove the existence of large classes of initial data satisfying the constraints for the spherically symmetric EinsteinVlasov-Maxwell system. These include data for which the ratio of total charge to total mass is arbitrarily large.

Two models, one assuming a massive dilaton and the other a massless dilaton, are used to calculate the equivalence violations of the spectrum of atoms. These are then compared and conclusions drawn.
