Scientific paper

Redshift distortions, both geometrical and kinematical, of quasar clustering are simulated, for the Two-Degree Field QSO Redshift Survey (2QZ), showing that they are very effective to constrain the cosmological density and equation of state parameters, Omega_{m0}, Omega_{x0} and w. Particularly, it emerges that, for the cosmological constant case, the test is especially sensitive to the difference Omega_{m0} - Omega_{Lambda 0}, whereas, for the spatially flat case, it is quite competitive with future supernova and galaxy count tests, besides being complimentary to them.
